 Hello,

 When I try to compile and link a Windows program using gcc that is in
B20 I get the following warning when I link:

warning: cannot find entry symbol _WinMainCRTStartup; defaulting to
00401000

 The exe file is created and I can run the program. But how sure can I
be that the program works OK. Anyone who knows how to fix this?

 The mainfile containg the WinMain() looks like this:

#include <windows.h>

int STDCALL WinMain( HINSTANCE tCurrInstance,HINSTANCE
tPrevInstance,LPSTR cpCmdLn,int iSM )
{
  ...
}

 My makefile looks like this:

CXXFLAGS=-O3
CPPFLAGS=-I.

LDFLAGS=-s -mwindows
LDLIBS=-lstdc++

OBJS=devapp.o application.o menu.o module.o msghandler.o window.o

..SUFFIXES: .cpp

..cpp.o:
	$(COMPILE.cc) $< $(OUTPUT_OPTION)

devapp.exe: $(OBJS)
	$(LINK.o) $^ $(LOADLIBES) $(LDLIBS) -o $@

clean:
	$(RM) *.o *.exe
