Erik M. Bray 2607639992 Improve error handling in /proc/[pid]/ virtual files.
* Changes error handling to allow /proc/[pid]/ virtual files to be
  empty in some cases (in this case the file's formatter should return
  -1 upon error, not 0).

* Better error handling of /proc/[pid]/stat for zombie processes:
  previously trying to open this file on zombie processes resulted
  in an EINVAL being returned by open().  Now the file can be read,
  and fields that can no longer be read are just zeroed.

* Similarly for /proc/[pid]/statm for zombie processes.

* Similarly for /proc/[pid]/maps for zombie processes (in this case the
  file can be read but is zero-length, which is consistent with observed
  behavior on Linux.

		   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.
