Cygwin and TTM Tex converter won't compile (gcc) - Mailing list pgsql-cygwin

I just installed Cygwin and also the gcc compiler package.
I have download a TTM LaTeX converter compiler that I was hoping would work
with Cygwin.  I followed instructions to compile ttm with the gcc compiler and
get the following message:
/usr/lib/gcc-lib/i686-pc-cygwin/3.3.1/../../../libcygwin.a(libcmain.o)(.text+0x7
a): undefined reference to `_WinMain@16'
collect2: ld returned 1 exit status

Is this enough info to get some help?

Thanks,
Charles
