Corinna Vinschen 4889f730c1 Reduce stack pressure throughout Cygwin
* dcrt0.cc (initial_env): Reduce size of local path buffers to
        PATH_MAX.  Allocate debugger_command from process heap.
        (init_windows_system_directory): Very early initialize new global
        variable global_progname.
        * dll_init.cc (dll_list::alloc): Make path buffer static.  Explain why.
        (dll_list::populate_deps): Use tmp_pathbuf for local path buffer.
        * exceptions.cc (debugger_command): Convert to PWCHAR.
        (error_start_init): Allocate debugger_command and fill with wide char
        strings.  Only allocate if NULL.
        (try_to_debug): Just check if debugger_command is a NULL pointer to
        return.  Drop conversion from char to WCHAR and drop local variable
        dbg_cmd.
        * globals.cc (global_progname): New global variable to store Windows
        application path.
        * pinfo.cc (pinfo_basic::pinfo_basic): Just copy progname over from
        global_progname.
        (pinfo::status_exit): Let path_conv create the POSIX path to
        avoid local buffer.
        * pseudo_reloc.cc (__report_error): Utilize global_progname, drop local
        buffer.
        * smallprint.cc (__small_vsprintf): Just utilize global_progname for
        %P format specifier.
        (__small_vswprintf): Ditto.
        * strace.cc (PROTECT): Change to reflect x being a pointer.  Reformat.
        (CHECK): Ditto.  Reformat.
        (strace::activate): Utilize global_progname, drop local buffer.
        Fix formatting.
        (strace::vsprntf): Reduce size of local progname buffer to NAME_MAX.
        Copy and, if necessary, convert only the last path component to
        progname.
        (strace_buf_guard): New muto.
        (buf): New static pointer.
        (strace::vprntf): Use buf under strace_buf_guard lock only.  Allocate
        buffer space for buf on Windows heap.
        * wow64.cc (wow64_respawn_process): Utilize global_progname, drop
        local path buffer.

		   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.
