Try using strip, part of the binutils package.  This is what I did:

 $ cat >hello.cpp <<EOF
#include <cstdio>

int
main()
{
  printf("hello, world!\n");
}
EOF
 $ i586-mingw32msvc-g++ hello.cpp -o hello.exe
 $ i586-mingw32msvc-strip --strip-all hello.exe

The result is 4608 bytes using GCC 4.2.1.  Note that I have not used the 
C++ standard library, since GCC links elements of this library statically 
into the executable, producing a much larger result.
