From ba94682838272afc87b73833c02aaf6cea40815e Mon Sep 17 00:00:00 2001
From: Corinna Vinschen <corinna@vinschen.de>
Date: Wed, 12 Sep 2001 17:46:37 +0000
Subject:         * Makefile.in: Build wincap.o.         * wincap.cc: New file.
         * wincap.h: Ditto.         * autoload.cc: Add dynamic load statement
 for `CreateHardLinkA'.         * dcrt0.cc (os_being_run): Eliminated.        
 (osname): Ditto.         (iswinnt): Ditto.         (set_os_type): Ditto.     
    (dll_crt0_1): Call wincap.init() instead of set_os_type().        
 (_dll_crt0): Ditto.         * environ.cc (set_chunksize): New function.      
   (parse_thing): `forkchunk' setting now invokes function `set_chunksize'.   
      * fork.cc (chunksize): Eliminated. Moved to be member of wincap.        
 * host_dependent.h: Removed.         * syscalls.cc (_link): Try using
 `CreateHardLinkA' first, if available.         * cygheap.cc, dcrt0.cc,
 delqueue.cc, dir.cc,         environ.cc, fhandler.cc, fhandler.h,
 fhandler_console.cc,         fhandler_mem.cc, fork.cc, mmap.cc, net.cc,
 pinfo.cc, pinfo.h,         security.cc, syscalls.cc, sysconf.cc, syslog.cc,
 thread.cc,         times.cc, tty.cc, uinfo.cc, uname.cc, winsup.h: Use new
 wincap         capability check throughout.         * winsup.h: Include
 wincap.h. Eliminate extern declarations of         `os_being_run' and
 `iswinnt'. Eliminate `os_type" definition.         *
 include/cygwin/version.h: Bump version to 1.3.4.
