From 5835f2cf8dfb01b93c233bfb5e486482a545aded Mon Sep 17 00:00:00 2001
From: Christopher Faylor <me@cgf.cx>
Date: Fri, 31 Aug 2001 05:06:14 +0000
Subject: * cygwin.sc: New file -- linker script for building cygwin DLL. *
 Makefile.in: Use linker script to control location of cygheap. * cygheap.cc
 (buckets): Make static. (init_cheap): Remove special iswinnt handling. 
 Allocate cygheap at a fixed location.  Display more info when allocation
 fails. (cygheap_fixup_in_child): Try harder to move cygheap to correct
 location. Display more info when allocation fails. * fhandler.h
 (fhandler_socket): Add macros for tracking socket shutdown state. * net.cc
 (cygwin_shutdown): Set appropriate shutdown value for future use. * select.cc
 (select_stuff::cleanup): New method. (cygwin_select): Call cleanup explicitly
 to avoid a race. (select_stuff:~select_stuff): Call cleanup chain via cleanup
 method. (fhandler_socket::select_read): Set *_ready when shutdown has been
 called on the socket. (fhandler_socket::select_write): Ditto.
 (fhandler_socket::select_except): Ditto. * winsup.h: Move NO_COPY to "COMMON"
 section. * autoload.cc (wsock_started): Avoid initializing NO_COPY value. *
 sigproc.cc: Remove initialization from NO_COPY variables. (sigproc_init):
 Initialize sig_loop_wait here, rather than via initialization.
 (subproc_init): Initialize proc_loop_wait here, rather than via
 initialization.
