problems building GUI application

[Axel Riese]

Hi all !

Concerning the discussion on the WinMainCRTStartup-warning:
 
> The Warning is issued because there is no WinMainCRTStartup in the cygwin32
> library, however crt0.o which is the first thing that is linked in by specs
> has the proper entry point (mainCRTStartup), which always gets put at

I get the same warning with gcc, but all the programs (seem to) work. 
 
> g++ -o test.exe test.cpp -luser32 (works fine no warnings)
> g++ -o test.exe test.cpp -luser32 -Wl,--subsystem,windows (works but gives
> the warning)
 
My solution is:

Replace the -Wl option by

      -Wl,--subsystem,windows,-e,mainCRTStartup

and you don't see the warning anymore.
