Corinna Vinschen d59d4877f8 Cygwin: define FILE as struct __sFILE64, not as __sFILE
Until Cygwin 3.3.6, we define __LARGE64_FILES unconditionally, so we
were using the type __sFILE64 even for 64 bit.  That was lazy and wrong.
so commit 2902b3a09e0a ("Cygwin: drop requirement to build newlib's
stdio64") tried to fix that.

Unfortunately this patch forgot to take the exposure of the typename
__sFILE64 in userspace into account.  This leads to trouble in C++ due
to name mangling.

Commit 0f376ae22036 tried to fix this by just renaming __sFILE to
__sFILE64 by using a macro.  While __sFILE and __sFILE64 are the same
size, they are not exactly congruent.

To avoid backward compatibility problems, make sure to define FILE
as the  real __sFILE64, and make sure that __sFILE is not defined at
all on Cygwin.

Fixes: 0f376ae22036 ("Cygwin: rename __sFILE to __sFILE64 for backward
compatibility")

		   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

COPYING.LIB in the various directories, for a description of the

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