(Sorry if you've seen this before but I sent it to bug-gnu-emacs
not realising that bug-gdb existed)

In GDB 2.7 on sibyl (usg-unix-v)

This is not so much a bug report as a contribution to support running
GDB on vanilla system 5 systems (the National Semiconductor port to
be precise). Sorry if this is not the correct address for this sort of
thing but I don't know of any where else to send it.

The changes are as follows:

System V support:
	This has been done rather in the style of emacs. There is a new
	file called sysdep.c which contains routines to emulate under
	system V, BSD specific functions. There is also a new include
	file, config.h, which contains operating system dependent
	definitions. Param.h could have been used for this but it seemed
	cleaner to keep param.h for the really implimentation specific
	stuff.

Floating Point printing:
	The way GDB behaved with INVALID_FLOATS was pretty unfriendly. If
	it found an invalid float while printing a structure, or union etc,
	it printed a message and gave up. The user might at want to know
	a) what is in the other fields of the structure, and b) what the
	hex code of the INVALID_FLOAT is. Both these enhancements have
	been implimented.

Coff file support:
	There was a bug in the handling of COFF symbol tables. It could
	sometimes use the tag field of an auxillary entry when there was
	nothing valid there. That code has been tightened up. Also, at least
	on this (NS Sys V) system it is possible for bad C code to generate
	coff files with bad symbol tables. Gdb, as distributed, contained
	multiple definitions of some variables and cc/as/ld generated a bad
	symbol table. When I did "gdb gdb" I got a core dump.  I have
	added some code which does some sanity checking of tag values
	which makes it possible to still work with such bad files. I have
	also fixed the multiple definitions in GDB.

NS32k Support:
	I have altered ns32k-pinsn.c to support printing invalid
	floating point operands in the style <<invalid float (0x....)>>.

NS System V specific support:
	Such things as function prologs and offsets in the kernal user area
	have been supported by providing m-ns5.h and m-ns5init.h.

I think I have introduced these changes without breaking anything else but
I don't have access to all the other machines/systems so I can't be 100%
certain I haven't stuffed up. I have tried to make changes in keeping
with the style of the rest of the code but feel free to alter/incorporate
these changes as you see fit. (No doubt you will do that anyway :-) ).

There are 5 parts because outgoing overseas mail from here must be
less than 25k. Part 1 contains a shar archive containing the new
files. Parts 2 to 5 contain shar archives of the patch files to make
the changes to the the existing files. The patch files are context
differences.
