Here is a patch for the changes and additions I've made to gdb 4.7 for
Interactive Systems (SunSoft) Unix 2.2 and 3.0.  With these changes,
you can say "configure i386-isc" and it makes all the correct build
files.

When building gdb with gcc (make "CC=gcc -posix -O") you will get a
warning on nearly every file about redeclaration of NULL.  You can
ignore the warnings.  I personally made changes to my system header
files "stdio.h", "sys/param.h", "sys/unistd.h" to conditionally define
NULL.

Two other minor additions of mine are these:

    o The command "info float" is back.  This was present in gdb 3.x,
    but was never made to work in 4.x for i386.

    o The instance pointer "this" is (at last) available when
    debugging C++ using COFF object files.

+ Thu Oct 29 10:12:09 1992  Richard L. Krehbiel  (rich@friend.kastle.com)
+ 
+ 	* coffread.c (process_coff_symbol): Added code to handle some C++
+ 	specific internal symbols.
+ 
+ 	* config/i386isc.mt: New file for ISC unix
+ 
+ 	* config/i386isc.mh: New file for ISC unix
+ 
+ 	* configure.in: Added cases for ISC unix host and target
+ 
+ 	* i386v-nat.c: Added working code for "info float", adapted from
+ 	gdb 3.5.  This was never updated for 4.x, until it finally
+ 	disappeared in 4.7; well, here it is again.
+ 
+ 	* infcmd.c: Added #include "nm.h" which contains the definition of
+ 	FLOAT_INFO.
+ 
+ 	* nm-i386isc.h: New file for ISC unix
+ 
+ 	* xm-i386isc.h: New file for ISC unix
+ 
+ 	* source.c (mod_path): Posix apparently has different definitions
+ 	for struct stat.st_mode; at least with ISC, (st.st_mode & S_IFMT)
+ 	becomes S_ISDIR(st.st_mode).  This permits build with gcc -posix
+ 	under ISC.
