the job. -3dfx doesn't get a package built right now, there
are...obstacles.
acinclude.m4, configure.in, Makefile.am: -sgl is detected separately from
-sdl now, and HAVE_XMESA is no longer in use.
remove the INCLUDELIBS blocks
include/win32/version.h:
ws changes. don't know why it's there in the first place (or generated
by configure, but too bad)
still has to be in CVS, because Win32 people generally won't be able to
rebuild it).
configure.in: Cleanups to the DGA, VidMode, and sound detection code.
Makefile.am: Cleanups to sound code, to allow 'make dist' to work.
