	of information).

* gdb.base/overlays.exp: Record addresses of overlay
functions in TCL variables rather than in GDB variables,
to avoid having GDB convert them to pointers (with loss
of information).
* gdb.base/d10v.ld: Merge in several years worth of
default linker script changes.
* gdb.base/long_long.exp: Add check for sizeof (long double).
