* Makefile.in (fold-const.o): depend on $(RTL_H).
* cplus-dem.c: Include config.h if it exists. Also, only
prototype malloc/realloc if we can't get stdlib.h.
* fold-const.c: Include rtl.h to get the prototype for
`set_identifier_local_value'.
* loop.c (express_from_1): Remove unused variable `tmp'.
(combine_givs): cast the first argument of bzero to char *.
* toplev.c (display_help): Remove unused variable `looking_for_start'.
Add explicit braces to avoid ambiguous `else'.
