From Jim Blandy  <jimb@redhat.com>
        * gdb.base/foo.c (foox): Remove section attribute; the linker
	script can handle this instead.
	* gdb.base/bar.c (barx): Same.
	* gdb.base/baz.c (bazx): Same.
	* gdb.base/grbx.c (grbxx): Same.

        * gdb.base/overlays.exp: New test: check that GDB's manual overlay
	manager doesn't automatically unmap overlays unnecessarily.
