	    with final tuning by Bryce McKinlay

	* configure.in: Add support for --enable-threads=posix on FreeBSD.
	* configure: Rebuilt.

2001-05-01  Jeffrey Oldham  <oldham@codesourcery.com>

	* gc_priv.h (UNLOCK): Change type of GC_noop1 argument.
	(GC_noop1): Change declaration to take one argument.

2001-04-26  Alexandre Oliva  <aoliva@redhat.com>

	* configure.in: Obtain THREADS with `gcc -v'.
	* configure: Rebuilt.

2001-04-05  Hans Boehm  <hans_boehm@hp.com>

	* misc.c: Back out buggy changes to stack clearing code.
	Reduce CLEAR_SIZE to 1/4 of original value to reduce time
	spent clearing memory.

2001-04-04  Hans Boehm  <hans_boehm@hp.com>

	* finalize.c:
	- Accomodate finalization requests for static objects.
	  (Will be required by hash synchronization.  May be needed
	  in some configurations now.)

	* gc_priv.h:
	- Define MIN_WORDS.  All allocation requests are rounded
	  up to at least this size.  Removes a subtle assumption that
	  Java objects have a 2 word header.

	* gcconfig.h:
	- Adjust Linux/IA64 configuration for non-ancient kernels.
	  (Necessary fix for IA64.)

	* linux_threads.c:
	- Fix syntax error in currently unused code.  Will be needed
	  for Linux/PA-RISC.

	* malloc.c:
	- Handle MIN_WORDS.

	* misc.c:
	- Handle MIN_WORDS.
	- Change stack cleaning code to typically clear about one tenth
	  the memory it used to in the threads configuration.  Occasionally
	  still clear more.  (This is really a fix for a long-standing
	  and fairly significant performance bug with threads.)

	* os_dep.c:
	- Fix the code for finding the beginning of the data segment under
	  Linux.  I believe this is necessary for some IA64 Linux
	  distributions.  It will also helo other platforms, though those
	  may additionally require a gcconfig.h adjustment.  (This basically
	  works around the absence of a data_start or __data_start
	  definition in glibc.)

	* test.c:
	- Handle rounding due to MIN_WORDS.

2001-03-22  Tom Tromey  <tromey@redhat.com>
