* hp300ux-nat.c: Update copyrights.

* mipsread.c (parse_partial_symbols):  Complain about block
indexes that go backwards.  Fix from Peter Schauer.
* symfile.c (syms_from_objfile, symbol_file_add):  Allow a
symbol-file that has no linkage symbols to be read.
* tm-rs6000.h, xm-rs6000.h: (SIGWINCH_HANDLER and friends):  Move
from tm- file to xm-file, since they're host dependent.
* valarith.c (value_binop):  Typo.
