[Opencxx-users] Make error on Cygwin

[Dominic H. <dom...@re...>]

When I downloaded Open C++ and tried to build it on Cygwin, configure ran
ok, but make resulted in the output below. libcmain.o has an unresolved
reference to _WinMain@16.

Environment: Open C++ Version 2.7, Cygwin version 1.5.5-1, Windows XP
Professional.

I tried hacking libcygwin.a, adding libscrnsave.a, which defines the symbol,
but this, not surprisingly, resulted in even more unresolved references.

Has anyone seen this error?
