* Makefile.in (xcoffread.o): Depend on partial-stab.h.

Browse Source 
* xcoffsolib.c (sharedlibrary_command): New command.
	* xcoffsolib.c (solib_info): Call xcoff_relocate_symtab.
	* xcoffsolib.c: Miscellaneous cleanups.

	* partial-stab.h: Ignore symbol descriptor '-' (for local
	variables with negative type numbers) without complaint.

	* rs6000-nat.c (vmap_ldinfo): Use bfd_stat rather than our own
	local emulation thereof.  Remove unused variable ostart.
