I did the above suggestion.  Try the attached.

This for some reason uses abort, malloc and free from msvcrt.dll!! 
Probably because of one of the other libraries.  This ``ld -o hello.exe 
hello.o /mingw/lib/crt2.o /mingw/lib/gcc-lib/mingw32/3.2.3/crtbegin.o 
-L/mingw/lib/gcc-lib/mingw32/3.2.3 -L/samo/mingw/bld/cygwin -L/mingw/lib 
-lmingw32 -lgcc -lmsvcr70 -lmingwex -luser32 -lkernel32'' resolved that 
problem.
