We might also want to consider removing:
        m68*-rom68k-*
        m68*-*bug-*

They all build, in fact they are all aliases to the generic embedded
m68k target.  If I recall corectly, these targets exist because back
in the pre-libgloss BSP days, newlib contained code for eval boards
with these ROM monitors so an entire separate toolchain (including
compiler, binutils, gdb, etc.) was built when only a tiny bit of code
was different.  

These are other aliases that don't make sense today:
        m68*-monitor-*
        m68*-est-*

I think so, but I haven't seen the message I sent two days ago...

Yes, that what "Fix:" was meant for, I believe.

Here's the stuff I get from "man CC" on SunWorkshop 5 C++:

Note that -compat=5 (which lets me use STL) will set the __cplusplus macro
to "199711L".  I don't know if that helps in determining which ABI those
guys are following.  Also, I tried to compile helloworld.cpp with -g and see
if the newest snapshot (23/Mar/2001) could debug it without me resorting to
-xs and it cannot.  Is there an option or config.h option that I need to
enable psymtab stuff?


     -compat[=(4|5)]
               Sets the compiler to be compatible with 4.0.1,
               4.1, and 4.2 compilers; or with full 5.0. This
               option controls the preprocessor __cplusplus
               macro.

               The C++ compiler has two principal modes.  One
               accepts the semantics and language defined by the
               Annotated C++ Reference Manual (ARM) and used in
               the 4.2 compiler (the compatibility mode, -com-
               pat=4).  The other accepts constructs according to
               the ANSI/ISO standard (standards mode, -compat=5).
               These two modes are incompatible with each other
               because the ANSI/ISO standard forces significant,
               incompatible changes in name mangling, vtable lay-
               out, and other ABI details. These two modes are
               differentiated by the -compat option as shown in
               the following values.

               Value          Meaning

               -compat=4      Compile for compatibility with C++
                              4.0.1, C++ 4.1, and C++ 4.2 (Sets
                              __cplusplus macro to 1.)

               -compat=5      Compile with full C++ 5.0 features.
                              (Sets __cplusplus macro to
                              199711L.)

               Defaults:

               If the -compat option is not specified, -compat=5
               is assumed.  If only -compat is specified, -com-
               pat=4 is assumed.

               Interactions:

               The -xarch=v9 option and the -compat[=4] option
               are not supported when used together.

That is the "partial symtab" (psymtab) code.

Recent snapshots of gdb, and the current CVS version of gdb, operate with
the new multi-vendor C++ ABI:

  http://reality.sgi.com/dehnert_engr/cxx/cxx-summary.html

If you could provide a URL or an ISO reference number for that "ISO/ANSI
ABI standard", I could check if it's the same as the "new ABI" standard
that we're working on supporting.

Nope.
It's automagic.

You are misreading it. All this means is that they changed their ABI to be
able to support the ISO standard, not that they are using a standard ABI.
They are most certainly not.  We have 0 support for their ABI, so you
won't be able to debug in any useful way.
