gcc and gdb config files for stabs in coff on 386 System V systems

I'm enclosing configuration files for gcc and gdb for use on 386
System V systems with my "stabs-in-coff" patches for gas and gdb.
I'd appreciate it if people would try these out and let me know the
results. If the results are good, I'll include these in the next
release of the "stabs-in-coff" patch set.
If you do not already have the stabs-in-coff patch set, it may be
obtained via either ftp or uucp as follows:
UUCP: osu-cis!~/gnu/coff/gnu-coff.tar.Z
FTP: tut.cis.ohio-state.edu:/pub/gnu/coff/gnu-coff.tar.Z

X
X UPDATE.README This file
X tm-i386gcoff.h a gcc config file for 386 system V sytems.
X m-i386gcoff.h a gdb config file for 386 system V sytems.
X gcc-patches an update to "config.gcc"
X gdb-patches an update to "config.gdb"
X bugfix.patch a small bug fix including a patch to
X dbxread.c that should be applied AFTER the
X patches you've already applied from the
X stabs-in-coff patch set.
X
XFor the time being, the config files listed above should be
Xconsidered "test versions". If reports are good, I'll include them in
Xthe next version of the coff patch set.
X
XThe bugfix patch applies to all systems using the coff patches,
Xnot just 386 systems.
