Corinna Vinschen 4de8596b8e Fix __getreent function for Cygwin
So far the lib function __getreent always returned _impure_ptr.  On Cygwin
this is only correct after _impure_ptr got initialized.  The inline
function in include/cygwin/config.h always returns the right _reent ptr,
though.

After introducing per-thread locales, the __getreent function is called
prior to initialization of _impure_ptr (from dll_crt0_0) to access the
locale pointer, which leads to a crash.

Fix the __getreent lib function for Cygwin to return the correct _reent
pointer all the time.  Rename inline function to __inline_getreent
and introduce a macro __getreent calling the inline function.  Change
the lib function __getreent to call __inline_getreent on Cygwin.

		   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.
