	* gdb.t00/teststrategy.exp: For p "foo", remove sun4 XFAIL (see
	PRMS 1823; the bug still exists but isn't reproduced by this test
	anymore), and remove rs6000 XFAIL (the bug is fixed).

	* gdb.t03/ptype.exp: Comment out a lot of tests which are basically
	duplicated from whatis.exp.  For those that are left, accept
	"long", "long int", or "int" for long variables (whatis.exp already
	has an XFAIL for "int", so no need to fail it here).

	* gdb.t02/whatis.exp, gdb.t10/crossload.exp:
	Deal with GCC's names for types now that GDB uses the compiler's names.

	* gdb.t02/{Makefile.in,gdbme.c,whatis.exp}:  If not GCC, do some
	setup_xfail's for sunos4.  If we #defined the signed keyword away,
	don't expect GDB to know that char it is signed.

	* gdb.t00/teststrategy.exp: Update for symbolic signal names.
