Fixing what? I'm not sure I have write access to gdb. The problem is PR35457 and it happens if toplevel make is invoked with CFLAGS "-O2 -g", but it invokes subconfigures with "-O2 -g " (typically as a result of expanding "-O2 -g $(SOMETHING)"). Without the fix the subconfigure would exit with an error; with the fix it will see that the difference is limited to whitespace and go on anyway. This bugfix is already there in Autoconf 2.62, but until we upgrade we have to keep it in the tree. Paolo
