Patrick Palka 2093d2d314 Don't truncate the history file when history size is unlimited
We still do not handle "set history size unlimited" correctly.  In
particular, after writing to the history file, we truncate the history
even if it is unlimited.

This patch makes sure that we do not call history_truncate_file() if the
history is not stifled (i.e. if it's unlimited).  This bug causes the
history file to be truncated to zero on exit when one has "set history
size unlimited" in their gdbinit file.  Although this code exists in GDB
7.8, the bug is masked by a pre-existing bug that's been only fixed in
GDB 7.9 (PR gdb/17820).

gdb/ChangeLog:

	* top.c (gdb_safe_append_history): Do not call
	history_truncate_file if the history is not stifled.

gdb/testsuite/ChangeLog:

	* gdb.base/gdbinit-history.exp: Add test case to check that
	an unlimited history file does not get truncated on exit.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
