fold-const.c: Include "system.h" to get stdlib.h and stdio.h.
* fold-const.c: Include "system.h" to get stdlib.h and stdio.h.
(lshift_double): Add parentheses around + or - inside shift.
(rshift_double): Likewise.
(size_int_wide): Explicitly set type of `bit_p' to `int'.
* Makefile.in (fold-const.o): Depend on system.h.
