I sent a configuration enhancement some time ago, and received a reply
requesting more information.  Unfortunately, (delete lame excuse why I
lost your message), so I have included the original enhancement
below.  Specifically, your message requested (1) a change log entry,
and (2) an explanation of why I would create an include file that
included another include file.

1) Here it is:

Wed Dec  4 08:29:21 1996  David Thompson  <thomas@cs.wisc.edu>

	* Added configuration support for Solaris 2 x86 systems using gas
	and gdb, to allow inclusion of debugging information for g++
	with -g instead of -gstabs.

2) The configure script differentiates between generic x86 svr4 and
Solaris 2 x86 svr4 hosts.  The existing Solaris 2 config had the
following define:
	tm_file=i386/sol2.h

which is an include file that included the generic sysv4.h file (don't
blame me for this one - it was already there!).  So, I following the
existing method and created a sol2gdb.h which included sysv4gdb.h.
The important thing here is that the
	#define PREFERRED_DEBUGGING_TYPE DBX_DEBUG 

from sysv4gdb.h happens for solaris 2 x86 hosts when stabs is set to
yes.  Whatever include path you want to use is up to you.

Subject: Solaris 2 x86 configuration enhancement
Date: Wed, 13 Nov 1996 17:07:11 -0600


We have compiled many versions of gcc and would like to offer this
enhancement to the configuration.  Currently, g++ on solaris 2.x hosts
using gdb and gas requires -gstabs to include debugging information,
even with --with-stabs --with-gnu-as specified as configure options.
For generic i[345]86-*-sysv4* type machines, this has been corrected
with the configuration file .../gcc-2.7.2.1/config/i386/sysv4gdb.h and
its "#define PREFERRED_DEBUGGING_TYPE DBX_DEBUG" statement.  Up to
this point, however, this same ability has not been included fo
i[345]86-*-solaris2* | i[345]86-*-sunos5*r type hosts.  The patch is
very simple.  Here it is:
