arocc does not behave as expected during errors if -E (preprocess only) is set

[squeek502]

test.c:

#INCLUDE "invalid"

Built with -Doptimize=ReleaseFast, the preprocessed output is printed and a 0 exit code is returned:

> arocc -E test.c
.\test.c:1:1: error: invalid preprocessing directive
#INCLUDE "invalid"
^
1 error generated.
# 1 "test.c" 1
# 1 "<builtin>" 1
# 186 "<builtin>"
# 1 "<command line>" 1
# 1 "test.c" 2

> echo %errorlevel%
0

Built with -Doptimize=Debug, the preprocessed output is printed and a 1 exit code is returned:

> arocc -E test.c
.\test.c:1:1: error: invalid preprocessing directive
#INCLUDE "invalid"
^
1 error generated.
# 1 "test.c" 1
# 1 "<builtin>" 1
# 186 "<builtin>"
# 1 "<command line>" 1
# 1 "test.c" 2

> echo %errorlevel%
1

Expected behavior (any optimize mode):

> arocc -E test.c
.\test.c:1:1: error: invalid preprocessing directive
#INCLUDE "invalid"
^
1 error generated.

> echo %errorlevel%
1

Without -E, the expected behavior is present:

> arocc test.c
.\test.c:1:1: error: invalid preprocessing directive
#INCLUDE "invalid"
^
1 error generated.

> echo %errorlevel%
1
