Pedro Alves a4674e4efc Fix sequential gdb test runs
Sequential test runs are stopping prematurely like this:

 $ make check RUNTESTFLAGS="non-existing-program.exp server-exec-info.exp"

 Running /home/pedro/gdb/mygit/src/gdb/testsuite/gdb.server/non-existing-program.exp ...

default_gdb_init has this:

    # Unlike most tests, we have a small number of tests that generate
    # a very large amount of output.  We therefore increase the expect
    # buffer size to be able to contain the entire test output.  This
    # is especially needed by gdb.base/info-macros.exp.
    match_max -d 65536
    # Also set this value for the currently running GDB.
    match_max [match_max -d]

It's the second match_max that is erroring.  As that call does not
specify an explicit channel name with -i, expect defaults to
$spawn_id, which is pointing at a channel that is already gone.  (If
the spawn_id variable is not set, match_max defaults to
$user_spawn_id / stdin/out).

		   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.
