Hi,

I have some questions and want HELP. And I apologize my English.
I'm not sure my problem is because of gcc, binutils, or gdb, OR
because of our machine.

The problem is about debugging.

I'm working on SONY NWS-5000 running NEWS-OS 4.2.1aRD.
I made binutils-2.6, gcc-2.7.2 and gdb-4.15.1. Each was configured;

binutils)
	./configure --prefix=/usr/GNU (CC=cc)
gcc (and g77))
	./configure --prefix=/usr/GNU --with-gnu-as --with-gnu-ld
	(stage3/xgcc was installed)
gdb)
	./configure --prefix=/usr/GNU (CC=cc)

Each was found to be mips-sony-bsd by config.guess etc.

Gcc seems to be working well. But when the program compiled by this
gcc exits with core dumped, our dbx cannot handle 'core' as following:

nakaji@zeisei3$ dbx ./pdconv core 
dbx version 2.11
Copyright 1988, 1989 MIPS Computer Systems Inc.
Type 'help' for help.
Corefile produced from file "pdconv"
Child died at pc 0x404aa8 of signal : Segmentation fault
reading symbolic information ...
dbx: internal error: Proc symbol ($Lb1) without proc table entry
nakaji@zeisei3$ 

This is the first problem. 

Next, 'make check' of gdb fails. Much of this failure occurs when
handling 'core', for example (gdb.log),

backtrace
#0  0x56a498 in sigsetmask () at sigsetmask.s:14
#1  0x54e1f8 in rl_signal_handler (sig=2) at signals.c:161
warning: Hit heuristic-fence-post without finding
warning: enclosing function for address 0x7ffff07c
This warning occurs if you are debugging a function without any symbols
(for example, in a stripped executable).  In that case, you may wish to
increase the size of the search with the `set heuristic-fence-post' command.

Otherwise, you told GDB there was a function where there isn't one, or
(more likely) you have encountered a bug in GDB.
(gdb) FAIL:     backtrace through signal handler

Of cource this gdb cannot handle 'core' made from a program compiled
by /bin/cc.

Question:
1) What is the reason I cannot debug using these tools?
2) What should I do to solve these problem or to check what is
   happenning? 
3) Will mips-sony-newsos4 be supported in the future?

and
4) Binutils, gdb and some other utils don't have the target
   'uninstall' in their Makefile. Why?

Any help will be appreciated.
Thanks in advance.
