Corinna Vinschen 60d1eeac6c Cygwin: cwd: avoid releasing the cwdstuff SRW Lock twice
cwdstuff::set has a code snippet handling the case where a process
can't create a handle to a directory, e. g., due to permissions.

Commit 88443b0a22 ("cwdstuff: Don't leave from setting the CWD
prematurely on init") introduced a special case to handle this
situation at process initialization. It also introduces an early
mutex release, which is not required, but ok, because we're in the
init phase. Releasing the mutex twice is no problem since the mutexes
are recursive.

Fast forward to commit 0819679a7a ("Cygwin: cwd: use SRWLOCK
instead of muto"). The mechanical change from a recursive mutex
to a non-recursive SRWLOCK failed to notice that this very specific
situation will release the SRWLOCK twice.

Remove the superfluous release action. While at it, don't set dir to
NULL, but h, since dir will get the value of h anyway later on.
Setting h to NULL may not be necessary, but better safe than sorry.

README

		   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.
