Re: [RFC] GDB Hurd Fixes

[David Michael]

Hi,

(Copying gdb-patches this time.)

Here is an updated patch to successfully build GDB after today's
Hurd/mig changes.

The awk script changes handle the "auto" keyword being dropped from
mig output, and that an "#if TypeCheck" line appears before
arg_check_name is defined in some new functions.

The gnu-nat.c changes define functions for the new process_reply.defs entries.

I'd appreciate any feedback or suggestions for getting GDB building on
current Hurd again.

Thanks.

David
