* config/tc-ppc.c (ppc_frob_symbol): Don't create an aux entry for
an absolute symbol.
Tue Oct 3 12:18:19 1995 Ian Lance Taylor <ian@cygnus.com>
* config/tc-m68k.c (isbyte): Accept all values from -65536 to
+65535, so ~VAL will not be rejected.
* cond.c (s_endif): Call demand_empty_rest_of_line. In MRI mode,
skip characters after the pseudo-op.
(s_else): Likewise.
