	gdb.disasm/{Makefile.in, configure.in}, gdb.stabs/{Makefile.in, configure.in},
	gdb.threads/{Makefile.in, configure.in}: Major reworking for autoconfig.
	* aclocal.m4, configure, gdb.base/configure, gdb.c++/configure,
	gdb.disasm/configure, gdb.stabs/configure, gdb.stabs/default.mt : New files.
	* config/unix-gdb.exp:  Make GDB global.

	gdb.disasm/{hppa.exp, sh3.exp}, gdb.stabs/weird.exp: Change continues
 	to returns as necessary, arrange for test to compile own testcase executable.
	* lib/gdb.exp: Changes for testsuite to compile own test cases.

	From Fred Fish (fnf@cygnus.com)
	* gdb.c++/classes.exp (test_pointers_to_class_members): Add
 	clear_xfail at end of test which might not call either pass or fail.
	* gdb.base/a1-selftest.exp: Add i*86-*-linuxaout xfail for
	"backtrace through signal handler".
