+
+       Changes from Jeff Law:
+
+       * config/tc-hppa.c (md_assemble): Fix typo.
+       (pa_ip): Delete unused variables and labels.  Do not check for 
+       unsigned values being < 0, it can't happen.
+       (is_same_frag): Return a value in recursive call case.
+       (pa_callinfo): Delete unused variables and labels.
+       (pa_comm): Likewise.
+       (pa_copyright): Likewise.
+       (pa_export): Likewise.
+       (pa_import): Likewise.
+       (pa_param): Likewise.
+       (pa_space): Likewise.
+       (pa_subspace): Likewise.
