Hi
Here the definition of the cmain.c program, part of libcygwin.a. This code
has a "main" entry point which is calling the WinMain by the end.... So the
question remains: Why g++/ld links with this "main" entry instead of the one
of the user's main program?

HMODULE x = GetModuleHandle (0);
char *s = GetCommandLine ();

s = nexts;
if (!nexts)
nexts = strchr (s, '\0');
else
nexts += strspn (nexts + 1, SP);
GetStartupInfo (&si);
return WinMain (x, 0, nexts,
((si.dwFlags & STARTF_USESHOWWINDOW) != 0
? si.wShowWindow
: SW_SHOWNORMAL));
}
