It allows it *only* for the link step, and not for the compile step (I'm going to submit a patch to make it accept in both cases). Here's an example: OK: % gcc -c foo.c % gcc -mwindows -o foo foo.o Not OK: % gcc -mwindows -o foo.c ld doesn't understand -mwindows. It's just a shortcut for GCC that passes the '--subsystem windows' option to ld as well as supplies some extra libraries needed for usual GUI "-luser32 -lgdi32 -lcomdlg32".
