Hi guys,

I update this patch follow cvs-head and do a small change about the testsuite.
Please help me review it.

Thanks,
Hui

2009-11-24  Hui Zhu  <teawater@gmail.com>

	* record.c (do_record_message): Add new argument "catch".
	(record_resume_error): Deleted.
	(record_resume): Call do_record_message with catch is 1.
	(record_wait): Deleted record_resume_error.
	Set status when do_record_message need stop the inferior.

2009-11-24  Hui Zhu  <teawater@gmail.com>

	* gdb.reverse/sigall-reverse.exp: Adjust.
