	* gdb.base/sigall.c (gen_*): Pass argument to handle_* to avoid
	compiler warning with dec alpha compiler.

	* gdb.base/commands.exp (if_while_breakpoint_command_test): Remove
	extra \n from gdb_test call (this explains why the prompt test

	(user_defined_command_test): Remove extra \n and prompt test.

	* gdb.base/sigall.c: If SIGABRT == SIGLOST, just act as if SIGLOST
	doesn't exist.  Likewise if SIGIO == SIGPOLL, pretend SIGPOLL
	doesn't exist.
	* gdb.base/sigall.exp: Remove special handling for SIGIO and SIGPOLL.
	Also remove alpha workaround, which turns out to be because
	SIGABRT == SIGLOST.
