Subject: 2002-04-12  Michael Snyder  <msnyder@redhat.com> 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.
