Followup-To: gnu.gcc.bug,gnu.gdb.bug

This bug report sent to both bug-gcc and bug-gdb.

There appears to be a bug in either the way fix-includes for gcc 2.2.2
works or the way the gdb-4.6 source expects it to act.

Included is the tail of a compile under gcc-2.2.2 w/o any patches,
fix-includes have been made, using CC=cc, which is to say:

	#!/bin/sh
	/usr/local/bin/gcc -traditional -fwritable-strings -fno-defer-pop $*

using the gmake command:

	gmake CFLAGS="-DGCC_MANGLE_BUG" all-gdb

from a Makefile configured via:

	./configure m68k-hp-bsd

The -DGCC-MANGLE_BUG is as per instructions in the gdb-4.6-gcc.patch.Z file.

I switched to CC=gcc, and it worked.

Looking at gdb-4.6/gdb/infcmd.c:879 did reveal the disturbing:

	const char * const reg_names[] = REGISTER_NAMES;

Anyhow, here's the tail:
