	* 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".

+    # This test is going to fail on all i*86 systems using an i*87.
+    # When returning a floating point value from a function, all known
+    # compilers do this via a `fldl' instruction, which pushes the floating
+    # value on the i387 stack. This causes two problems:
+    # a) Most i*86 targets do not store (or cannot store, see comment in
+    #    in i386v-nat.c:i386_register_u_addr) the floating point registers
+    #    to the target.
+    # b) gdb would have to figure out if the `fldl' instruction (or variants
+    #    of it) has already been executed. If not, it would have to simulate
+    #    a push instruction, as it is not enough to write the register,
+    #    the floating point `stack pointer' has to be updated too.
+    #    Do not expect this to get fixed anytime soon.
+
+    # This test also fails for sparc Solaris 2.3 & 2.4, but passes under 2.5
+    # At the time the `next' is issued, the floating point unit for the
+    # process is not yet initialized, and the storing of the floating
+    # point value to the floating point return register is ignored.
+    # Xfail it for current versions that are known to fail.  Presumably
+    # if some future version does initialize the floating point unit at
+    # process start, making this test pass, it will be for a version that
+    # is not xfailed.
