* Makefile.in (PREPROCESSOR_DEFINES): New macro.

(protoize.o):  Use PREPROCESSOR_DEFINES and DRIVER_DEFINES.
(unprotoize.o): Ditto.
(test-protoize-simple): Don't define STD_PROTO_DIR.
* protoize.c: Use PARAMS rather than PROTO.  Minor whitespace
changes to make 'test-protoize-simple' pass.
(STD_PROTO_DIR): Remove define.
(STANDARD_EXEC_PREFIX): Supply default define.
(standard_exec_prefix): New variable, init to STANDARD_EXEC_PREFIX.
(target_machine): New variable, init to DEFAULT_TARGET_MACHINE.
(target_version): New variable, init to DEFAULT_TARGET_VERSION.
(GET_ENV_PATH_LIST): New macro.
(default_syscalls_dir): No longer initialized to STD_PROTO_DIR.
(do_processing): Initialize default_syscalls_dir using new
macros.  Use it to initialize syscalls_absolute_filename.
