Toplevel configure script

(Yeah, as if there's more than one of them. ;-))

Just did a CVS checkout of WineX, and it appears that CVS was unable to 
merge somebody's changes to the configure script.  There are 4 different 
places with CVS's standard:

<<<<<<< configure
[contents of one revision]
=======
[contents of the other revision]
 >>>>>>> W.XYZ

comments (and it looks like one of these is nested, which tells me that 
it happened twice?).  ./configure itself failed to run, because that's 
invalid shell syntax (though it only caught the last one -- the rest 
were inside "cat <<_ACEOF >conftest.c ... _ACEOF" constructs, so they 
merely got put into the test C programs, and caused the test to fail).

I was able to rerun autoconf, and it compiled at least.  But somebody 
with write access to CVS might want to manually fix the script...

FYI.  No hurry, as it works here.  ;-)
