Corinna Vinschen 8d138c3f66 Cygwin: fix LC_CTYPE in global locale to be a real C.UTF-8 locale
https://cygwin.com/pipermail/cygwin/2022-December/252571.html

Cygwin's default locale is "C.UTF-8" as far as LC_CTYPE settings
are concerned.  However, while __global_locale contains fixed
mbtowc and wctomb pointers, the lc_ctype_T pointer is still pointing
to _C_ctype_locale, representing the standard "C" locale.

The problem with this is that the codeset name as well as MB_CUR_MAX
is wrong.

Fix this by introducing a new lc_ctype_T structure called
_C_utf8_ctype_locale, setting the default codeset to "UTF-8" and
MB_CUR_MAX to 6.  Use this as lc_ctype_T pointer in __global_locale
by default 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.
