I looked at
http://cvs.winehq.com/cvsweb/wine/tools/winegcc.c?rev=1.16
and see you don't have

#define selectany weak

Without that, you get compilation errors on my demo (and presumably
on the original poster's source code):

[dank at krunch dank]$ gcc -include msextensions.h bar.c foo.c
bar.c:3: warning: `selectany' attribute directive ignored
foo.c:1: warning: `selectany' attribute directive ignored
/tmp/ccFjkSf7.o(.data+0x0): multiple definition of `x'
/tmp/ccDWXV71.o(.data+0x0): first defined here
collect2: ld returned 1 exit status

Think winegcc should do -Dselectany=weak?
