What version of MinGW do you have? And especially of the MinGW runtime (i.e. 
the MinGW versions of the Windows runtime libraries)? These appear to be the 
source of the problem. DeleteObject and CreateCompatibleBitmap are in 
gdi32.lib (Microsoft) or libgdi32.a (MinGW).

The most obvious explanation is that your MinGW installation is incorrect or 
corrupt, since normally finding these libraries is no problem. My guess is 
that MSys doesn't know where MinGW is. You can fix this (see MinGW/MSys 
installation documentation).

Try adding the MinGW lib directory to your custom.py. Or tear MinGW/MSys out 
and reinstall them, but don't be in a big hurry to do that without trying 
other things first. You could try installing the MinGW runtime, and also 
verifying that you can link a test program, like this:

#include 

int main(int argc, char *argv)
{
    DeleteObject(0);
    return 0;
}

g++ main.cpp -o test.exe -lgdi32

The linker options are set in custom.py and SConstruct using statements such 
as:

environment.Append(LINKFLAGS = ['flag1', 'flag2'])

for static libraries, or for dynamic libraries:

environment.Append(SHLINKFLAGS = ['flag1', 'flag2'])

Hope this helps,
Mike
