Subject: Yet another undefined _WinMain16...
Date: Thu, 19 Jun 2003 08:01:11 +0000

I just downloaded the CygWin package, including gcc (MynGW) because I had been 
having no luck at all making MynGW work by itself on another machine.

I have a simple app that defines static int main (int argc, char **argv) {...}
Using the command 'gcc -o testit testit.c' generates the usual message:
/usr/lib/gcc-lib/i686-pc-cygwin/3.2/../../../libcygwin.a(libcmain.o
(.text+0x7c): undefined reference to `_WinMain AT 16'
collect2: ld returned 1 exit status

The FAQ and the CygWin mailing list indicated that there might be some 
advantage to renaming /usr/lib/libm.a to /usr/lib/libm.a.16bit but that had no 
effect. Since there's already a main() in the program, it looks as though some 
configuration file somewhere might be causing a problem, but I'm not sure 
where to look. If it helps, I did a gcc -v:
$ gcc -v

I haven't found any generic makefiles or anything of that sort. Anyone got a 
useful suggestion for a good place to look for the cause of this problem?
