Would that resolve your problem? It certainly > resolves mine. ./configure; make; ./configure; time make real 0m12.498s ./configure; make; time make real 0m0.976s make gdb.info; rm gdb.info; time make gdb.info real 0m0.425s I do not see the point playing with gdb.info build optimization. It makes the currently situation worse only by 3.4%. The same optimization should be applied first to version.in / version.c as currently whole gdb + gdbtui get relinked. This is outside of the scope of this patch. Or which operation would you like optimized? Regards, Jan
