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?
