Pedro Alves 4e18fe9cb3 Document pseudo-terminal and interrupting changes
This documents changes done in previous patches:

 - the fact that on GNU/Linux, GDB creates a pseudo-terminal for the
   inferior instead of juggling terminal settings.

 - That when the inferior and GDB share the terminal, you can't
   interrupt some programs with Ctrl-C.

 - That on GNU/Linux, you may get "Program stopped." instead of
   "Program received SIGINT" in response to Ctrl-C.

 - That run+detach may result in the program dying with SIGHUP.

I was surprised that we do not currently have a node/section
specifically to talk about interrupting programs.  Thus I've added a
new "Interrupting" section under the "Stopping and Continuing"
chapter, with some xrefs to other sections.

gdb/ChangeLog:

		   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.
