* configure.in (AC_CHECK_FUNCS): Check for strchr and strrchr.
* configure: Regenerate.
* config.in: Add #undef's for strchr and strrchr.
* protoize.c (toplevel): If we have rindex, but not strrchr, map
rindex to strrchr.
(file_could_be_converted): Use strrchr, not rindex since rindex is
not defined on Linux systems when _POSIX_SOURCE is defined.
(file_normally_convertible): Ditto.
(process_aux_info_file): Ditto.
(main): Ditto.
* rs6000.md (mov{sf,df} define_splits): When splitting a move of
a constant to an integer register, don't split the insns that do
the simple AND and OR operations, rather just split each word, and
