[RFC] GDB Fixes

[David Michael]

Hi,

Recent changes in mig/Hurd have broken GDB's build process.  I've
appended my changes here and would appreciate any feedback.
(Apologies if this is better sent to a GDB mailing list; I'm hoping
someone here can tell me if I'm doing something stupid with mig
output.)

The first part fixes an awk script after the "auto" keywords were
stripped from mig's output.  The patch adds another block that should
make it compatible with both old and new versions of mig.

The second part defines some process_reply.defs functions to bring it
in line with Hurd's 0845794f.  I assume these will just be unused
functions when building with old Hurd versions, but I haven't tested.

Can anyone comment on this?  (Also, sorry if this steps on any of the
other Hurd/GDB projects going on--I'm just trying to get a working
debugger again.)

Thanks.

David
