It all depends on what you're using, and you're not very specific.
If you're using mingw32ce, then odds are that you're not using many DLLs
as we don't distribute them yet. That's different for cegcc.
Also you mention C++. The C++ support has evolved a lot in gcc,
Microsoft is almost certain to have higher quality in some areas
(especially the libraries) there.
Apart from that, have you run "size" on the executables, and compared
the results ? Also you may be able to see more if you use objdump on
them. You should be able to use both these tools even on MS generated
executables.
Here is the output for a downloaded and a homegrown xwords. Note they
may not be exactly from the same source :-)

Surprisingly the smaller executable is the one compiled with cegcc !
