The patch also includes regenerated configure files.
OK, if you were asking permission. 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.
