Corinna Vinschen c0aa6ac30e Cygwin: NFS: create devices (especially FIFOs) as shortcut files
Creating real NFS symlinks for device files has a  major downside:
The way we store device info requires to change the symlink target
in case of calling chmod(2). This falls flat in two ways:

- It requires to remove and recreate the symlink, so it doesn't
  exist for a short period of time, and
- removing fails badly if there's another open handle to the symlink.

Therefore, change this to create FIFOs as shortcut files, just as on
most other filesystems.  Make sure to recognize these new shortcuts
on NFS (for devices only) in path handling and readdir.

		   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

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
