occ: preprocessing stringizer sometimes got confused by quotes
rtl: add mousewheel support to WIN32 headers
rtl: fix stdout & friends with CRTDLL.DLL
rtl: fix sprintf & family, there was a space between a negative sign and its number

Version 4.1.17:

occ: fix the macro preprocessor to handle a wider variety of standard cases
occ/dlpe/rtl: revert the import behavior, needed to be allowed to link to C-style functions without fully prototyping everything...
orc: further improve internationalization
orc: fix broken string table and language resource handling (neither case should need a resource id)
rtl: change definition of ffs(); RTL/DOS: fix CTRL-C and CTRL-BREAK to not crash

Version 4.1.16

occ: macro arguments were getting substituted twice
occ: loop invariant calculations could move floating point expressions, which doesn't work well on the x86 because they aren't real registers
occ: local definitions of a structure that is cyclical would cause a crash
occ: bad structure declarations such as this would crash the compiler:

struct nn
{
  struct nn *p, // note the comma
  int a;
};

oasm: allow '%%' style labels
ocl: used ONASM in compile-via-assembly mode instead make it use OASM

orc: treat BEGIN the same as '{' and END the same as '}'
orc: allow C-style escape sequence inside strings
rtl: fgets was going one character past the end of the supplied buffer...
rtl: fix custcntl.h to have A and W structure names
rtl: fix definition of wsprintf
rtl: fix wildargsw, needed hInstance.
rtl: fix dll startup routines, was crashing when dll created by the tools loaded

rtl: exit routines not being called, e.g. automatic end-of-program behaviors such as files being flushed when not explicitly closed would not occur
rtl: rewrote printf & family to handle "%s" using arbitrarily large strings...
rtl: fixed MSDOS debugger

Version 4.1.15

occ: support signed zero
rtl: fix a bug where flushing a file in text read mode could result in a seek to the wrong file position
rtl: fix integer to ascii functions to use lower case letters for hex, only do negative signs in base 10, buffer overflow problems.
rtl: add ffs() and 'strings.h' and related functions
rtl: fix definition of size_t in sys\types.h
rtl: fix isctrl('\0') to return true
rtl: fix isspace('\t') to return false
rtl: treat buffered strings as binary...
rtl: miscelleneous updates to floating point display handling, including improved handling of nans and signed zero

Version 4.1.14

occ: fix problem where registers used for long long calculations could sometimes collide
occ: fix new problem where sometimes function calls would cause the compiler to crash
occ: fix new problem where local statics could collide, resulting in a redefinition error, when they were previously declared external
occ: reorder commutative expressions to generate better code, needed especially to reduce the number of floating point registers in use simultaneously

Version 4.1.12

rtl: fix WIN32 header bug that caused CCIDE to not work reliably

Version 4.1.11

occ: remove import record from ASM file, when DLL name not specified
occ: fix problems with statements such as:
```
typedef void AA(int b);
AA ss,*tt;
ss(4);
tt(4);
```
the typedef wasn't processed right and it resulted in errors
occ: add __int8, __int16, __int32
occ, dlpe, rtl: adjust for optimized imports
rtl: work with RTL DLLs

Version 4.1.10

occ: problem with declaring things like void (*printf)(...) in a structure would cause a redefined identifier error
occ: problem with assigning to the first member of a structure, when the member was a pointer, would crash the compiler

Version 4.1.9

occ: there was a problem with sign extensions in statements such as p+=c where p is a pointer and c is a character value - the sign extension would be done after multiplying by the size of a pointer leading to overflow

Version 4.1.8

occ: 4.1.7 broke some programs with infinite loops
occ: fix problem where strength reduction could be incorrectly applied when induction variables of nested loops were multiplied together
occ: fix problem with division: sequences such as:
```
a = t %60
t = t / 60
b = t % 60
t = t / 60
```
would incorrectly generate code for:
```
a = t % 60
t = t / 60 / 60
b = t % 60
t = t / 60 / 60
```
because of bugs in dealing with the x86 IDIV instruction

Version 4.17

occ: comment out some test code that is no longer needed
occ: fix problems with functions returning a structured value

Version 4.16

occ: fix problem that broke the runtime library
occ: fix problems with statically initialized bit fields
occ: deal with zero-length anonymous bit fields properly
occ: more speedups
occ: deal with several crash conditions
occ: deal with some incorrect code generation problems
occ: fix some floating point problems

Version 4.15

oasm - fix problems with constants, structures, and improve code gen for move immediate to reg
occ - speed up compilations, fix bugs, add a branch optimization
omake - fix bugs
orc: allow integer values for resource types, e.g. for manifests

Version 4.1.4

oasm: some floating point instructions involving memory access were generated incorrectly
occ: floating point - use memory access more often
occ: floating point - change div by a constant into mul by a constant
occ: loops - generate code at the top of the loop to test the loop condition instead of branching to the bottom of the loop (while and for loops) and optimize such code away when possible.
occ: worked on constant propagation code, was not folding assignments
ocl: use OASM instead of ONASM
omake: fix problem where VPATH would not be considered if a file did not exist
omake: fix 'F' and 'D' suffixes on special macros, for example $@F and $@D

Version 4.1.3

occ: fix two crash conditions in code generator
occ: some algorithmic rewrites to get an order of magnitude speed improvement on large bulky functions.
occ: fix problem with register allocator, on very complex programs register usage could sometimes overlap when it shouldn't
occ: fix problem in static initialization when fixed point constants are stored as floating point constants: size of the storage did not match size when the value was loaded
occ: fix peephole optimization problem that caused code to disappear
occ: fix floating point global optimization to adjust properly for x86 FP unit
occ: fix register allocation/peephole optimization in the presence of infinite loops
occ: add the functionality to use two-character character constants
occ: fix packing of unions to work according to the windows standard...
occ: fix problems with cascaded shift operations
occ: fix problems with aliasing in the presence of assignments of structures
omake: dependencies were correctly qualified off VPATH, but when they showed up in a command the VPATH path was missing
omake: enable searching for implicit rules when explicit rules exist for dependencies but there are no commands
orc: add LOADONCALL parsing (doesn't do anything)
orc: scan for bitmap files etc... on the include path
rtl: utime.h is now in both include and include\sys for portability
rtl: add VOS__ constants to windows.h
rtl: toolchain and generated programs would crash if an environment variable was greater than 1024 bytes long
rtl: fix console mode of stdin to allow echoed line input on windows 7
rtl: fix getch() and friends - were broken because of the compiler union packing issue
rtl: rename winversion.h to winver.h

Version 4.1.2

oasm: was generating an error when a large number was used as a byte operand to a math instruction but it was in-range for a signed value.
occ: feature addition - OCC will look in its home directory for olink.exe
occ: prototype warnings - only warn once, remove superfluous warnings
occ: /O switch would add a .o extension to an executable and use it as an object file which resulted in duplicate modules being passed to the linker and linker errors. fix the /O switch to only register the exe name.
occ: if a continuation character '' was used in strings, and it was followed by a // style comment within the string, this generated parser errors.
occ: was filling out the entire BSS with zeros, which resulted in very large object files when there is a lot of static uninitialized data
occ: when compile fails, delete the output file
occ: correct code gen/register allocation/peephole optimization bugs
olink: documentation changed to use correct target names for windows targets
rtl: when the following was done in the source prior to including files:
#define size_t int
then there was a collision between string.h and memory.h
