<sys/types.h> is deprecated and all warnings being treated as errors

[guatedude2]

Since all warnings being treated as errors it fails to build on alarm (archlinux arm6, rpi zero rev 2):

# scons
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
CC      main.o
CC      mailbox.o
mailbox.c: In function 'mbox_open':
mailbox.c:275:13: error: In the GNU C Library, "makedev" is defined
 by <sys/sysmacros.h>. For historical compatibility, it is
 currently defined by <sys/types.h> as well, but we plan to
 remove this soon. To use "makedev", include <sys/sysmacros.h>
 directly. If you did not intend to use a system-defined macro
 "makedev", you should undefine it after including <sys/types.h>. [-Werror]
     if (mknod(filename, S_IFCHR|0600, makedev(100, 0)) < 0) {
             ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
scons: *** [mailbox.o] Error 1
scons: building terminated because of errors.

Solution replace <sys/types.h> with <sys/sysmacros.h> in file mailbox.c on line 40
