Fresco/Prague configure.ac,1.43,1.44

Update of /cvs/fresco/Fresco/Prague
In directory purcel:/tmp/cvs-serv20833/Prague

Modified Files:
	configure.ac 
Log Message:
A couple of buildsystem fixes:
 * Reactivated some old code from Havard: --enable-optimization and
     --enable-debugging should work again (closes bug45)
 * --enable-c++-demos renamed to --enable-cxx-demos: Looks like
      autoconf does not like + in options (closes bug173)
 * Toplevel Makefile should check for "Makefile" in the subproject's dirs:
      --disable-sdl should now work, even if builddir == srcdir       
      (closes bug209)
 * Remove -rdynamic flag: We need gcc > 3.0 now and I can't find any 
      documentation on this flag anymore (closes bug79)
 * Various small cleanups like replacing macros that are getting obsolete)
