win32gui: more splash screen integration
The Makefile have rip.uu/splash.uu added to them. However, this won't
work if you don't have splash.uu. Instead, just copy rip.uu or another
.uu and name it splash.uu. Make expects to have splash.uu present (at
least Borland's make). It doesn't add splash.uu decoding to the IDE
framework. It does a bit in winhack.rc and Makefile.bcc to bring
winhack.rc up to sync with Borland's compiler. If you don't like the
splash screen, then I'll have to redo that part of the patch apart from
the others.
1) Removal of bmp placement in binary directory in NT
2) No use of "intrinsic function" optimization in dsp
3) Compilation of resource file for NT Console
Untested on Borland yet. Tested on console/graphical/ide Microsoft C 6.0
