Update to 7.2d:

[7.2d]

2012-08-09  Ivan Maidanski <ivmai@mail.ru>

	* doc/README: Change version to 7.2d (rev. D).

2012-08-05  Ivan Maidanski <ivmai@mail.ru>

	* config.guess: Regenerate (by autoreconf -vif using autoconf-2.68,
	automake-1.11.1 and libtool-2.4).
	* config.sub: Likewise.
	* m4/libtool.m4: Likewise.

2012-08-02  Ivan Maidanski <ivmai@mail.ru>

	* misc.c (GC_clear_stack_inner): Use GC_approx_sp() instead of
	"dummy[0]" set to "&dummy" value (that worked as expected only for
	STACK_GROWS_DOWN case).

2012-08-02  Ivan Maidanski <ivmai@mail.ru>

	* alloc.c (min_bytes_allocd, GC_stopped_mark): Use GC_approx_sp()
	instead of "&dummy"; remove 'dummy' local variable.
	* dyn_load.c (GC_cond_add_roots): Likewise.
	* misc.c (GC_init): Likewise.
	* os_dep.c (GC_get_stack_base, GC_get_main_stack_base): Likewise.
	* pthread_stop_world.c (GC_suspend_handler_inner,
	nacl_pre_syscall_hook, __nacl_suspend_thread_if_needed): Likewise.
	* pthread_support.c (GC_thr_init): Likewise.
	* ptr_chck.c (GC_on_stack): Likewise.
	* win32_threads.c (GC_push_stack_for): Likewise.
	* extra/setjmp_t.c (main): Define volatile 'sp' local variable, store
	its address to it and use it instead of "&dummy"; remove 'dummy' local
	variable.
	* mach_dep.c (GC_with_callee_saves_pushed): Use volatile for 'dummy'
	local variable.
	* misc.c (GC_clear_stack_inner): Store address of volatile 'dummy'
	local array (i.e. 'sp' value) to its first element (and use it in the
	comparison of addresses) to prevent any harmful optimizations as C
	officially disallows comparisons of pointers to different objects
	(e.g., some Mac OS X clang releases might turn a conditional
	expression that uses 'dummy' address into a constant); update comment.
	* misc.c (GC_call_with_stack_base): Use "&base" instead of "&dummy"
	(it is safe to use address of base here); remove dummy variable.

2012-08-01  Ivan Maidanski <ivmai@mail.ru>

	* misc.c (GC_call_with_stack_base): Call GC_noop1 after fn()
	invocation to prevent a tail-call optimization.

2012-07-21  Ivan Maidanski <ivmai@mail.ru>

	* os_dep.c (GC_get_stack_base): Abort if pthread_stackseg_np fails
	(if GC_OPENBSD_THREADS).
	* pthread_stop_world.c (GC_suspend_all): Get correct stack_ptr by
	calling pthread_stackseg_np (subtracting ss_size from ss_sp) instead
	of retrieving it from OpenBSD pthread implementation-dependent context
	(if GC_OPENBSD_THREADS); remove comment.

2012-06-17  Ivan Maidanski <ivmai@mail.ru>

	* tests/initsecondarythread.c: Include "private/config.h" if
	HAVE_CONFIG_H (mostly to have GC_WIN32_PTHREADS defined for
	pthreads-w32 target).
	* tests/thread_leak_test.c: Likewise.
	* tests/threadkey_test.c: Likewise.

2012-06-16  Ivan Maidanski <ivmai@mail.ru>

	* tests/test_cpp.cc (WinMain): Prevent SEGV in strtok() by checking
	"cmd" WinMain argument for NULL (in that case "argc" local variable is
	set to 0).

2012-06-16  Ivan Maidanski <ivmai@mail.ru>

	* tests/test_cpp.cc (main): Call GC_set_all_interior_pointers(1)
	before GC_INIT to ensure that the collector considers pointers to
	object interiors as valid ones (such a pointer could emerge as
	a result of a type cast to subclass in case of multiple inheritance);
	add comment.
Updated devel/boehm-gc to 7.2d
Remove unnecessary hunk (was included upstream).

Update to 0.45.0
  Fix rare failures in "Clean" target. Thanks to David Holland!

  New configuration variable SEND_REPORT_FIRST was introduced.

  Boolean variables MASTER_MODE, CROSS_COMPILE, SEND_REPORT_FIRST
  accepts values true|yes|1 for logical TRUE and false|no|0 for
  logical FALSE. This may fix some hacks in single node setups.

  During upload rsync may unexpectedly fail due to connection
  failure. In order to resolve this problem, upload may be repeated
  several times. The following variables were introduced for this
  purpose: UPLOAD_PKGS_ATTEMPTS, UPLOAD_PKGS_PAUSE,
  UPLOAD_LOGS_ATTEMPTS, UPLOAD_LOGS_PAUSE.

  Progress messages now better illustrates internal structure of
  the build process.

  Option -a was added to distbb(1) in order to build updates for
  quarter releases more efficiently.

  stage_checks:
    - double underline in "checks" filename means _ in the report
      text, single underline means space.
    - one more check for broken pkg_summary (REQUIRES field).  It
      checks for libraries under /tmp, /home, /srv and /work
      directories.

  stage_upload_logs:
    - huge pkg_enriched_summary.txt is not uploaded

  README was updated

  Minor clean-ups
Add comment to patch-ab.
Updated pkgtools/distbb to 0.45.0
+ help2man-1.40.12, pkg-config-0.27.1, uim-1.8.2 [pkg/46840],
  vim-share-7.3.638 [pkg/46939], x264-devel-20120825.
Changes 0.27.1:
- Various fixes for using the internal glib snapshot. It should now be
  usable pretty much everywhere with the exception that universal
  builds are not supported on OS X.
- Remove usage of gettext from the internal glib to avoid gettext and
  libintl dependencies.
- Update internal glib snapshot to 2.32.4.
- Fix check for POSIX shell used in tests to work better.
- Handle spaces in autodetected prefix on Windows.
- Bugs fixed 3550, 51883, 52031, 53493.
Remove now unnecessary patch.
