I thought that gcc will figure the langauge based on the extension.
So g++ file.c would actually compile as a C file... But this may not
work for other compilers. We could do it ourselves in compile(),
choose $CC or $CXX based on the extension. However, I'm not sure it's
better than your solution. In fact, it's a lot more risky.

winegcc: Use $(CC) for building generated .spec.c

Hi,

Under v3.3.2, given a file a.c containing

int dwmain(int argc, char*argv) { return 1; }

I get:
[jon@home winegcc]$ gcc -c a.c && nm a.o
00000000 T dwmain
[jon@home winegcc]$ g++ -c a.c && nm a.o
00000000 T _Z6dwmainiPc

So it would appear not...

Cheers,
Jon
