Hello,

I'm not sure if this is the right mailing list for this patch but it modifies 
the top level directory of binutils-gdb for which I understand GCC to be the 
upstream. The purpose of this patch is to use PKG_CHECK_MODULES in 
config/debuginfod.m4 since debuginfod supports pkg-config. Otherwise the 
functionality of debuginfod.m4 is not changed by this patch. The rest of the 
changes involve renaming a debuginfod autoconf variable, removing an 
unnecessary call to AC_DEBUGINFOD in the top level configure.ac and the 
regeneration of files in gdb/, binutils/ and the top-level directory.

I can't ack the binutils or gdb directories.  But the toplevel and config/ bits
are fine.  Do you have commit privs to the GCC repo?  Do all these have to go in
together?  If so, that means we should coordinate commits and resyncing gcc, gdb
and binutils

I do not have commit privs to the GCC repo. It's better if all parts
are committed
at once to keep the files consistent.

I've reattached the patch and cc'd gdb-patches. Binutils and GDB folks, do
you have any concerns with this patch?

Thanks,
Aaron

Instead of inlining pkg.m4 into aclocal.m4, how about making
config/pkg.m4 and then using m4_include from gdb/acinclude.m4?
That's what gdb does for other shared m4 code.

Since it's debuginfo.m4 that is using PKG_CHECK_MODULES, can you put the include
of pkg.m4 in debuginfo.m4, instead of in {binutils,gdb}/configure.ac?

Otherwise, from GDB's point of view I think it looks good, unless Tom has some things to add.

Great. I can push to binutils-gdb but not gcc. Should I just push to
binutils-gdb for now or wait until the patch can be applied to both
repos at once?

I'm going to go ahead and push to binutils-gdb. Since these changes
should not affect gcc there shouldn't be any conflicts.
