Makefile.in (gcc.o, [...]): Depend on prefix.h.

        * Makefile.in (gcc.o, prefix.o, cccp.o, cpplib.o): Depend on prefix.h.
        * cccp.c: Include prefix.h, don't prototype prefix.c functions.
        (new_include_prefix): Constify char* parameters.
        * cppfiles.c (read_name_map): Likewise.
        (append_include_chain): Likewise.  Also, use a writable char* copy
        of parameter `dir' which we then modify, rather than using the
        parameter itself to store the new writable string.
        (remap_filename): Constify some variables.  Also, use a writable
        char* to store an allocated string which we will be modifying.
        * cpplib.c: Include prefix.h, don't prototype prefix.c functions.
        (cpp_start_read): Constify variable `str'.
        * cpplib.h (append_include_chain): Constify a char* parameter.
        * gcc.c Include prefix.h, don't prototype prefix.c functions.
        (add_prefix, save_string): Constify char* parameters.
        (fatal, error): Add ATTRIBUTE_PRINTF_1 to prototypes.
        * prefix.c: Include prefix.h.
        (get_key_value, translate_name, save_string, update_path,
        set_std_prefix): Constify various char* parameters and variables.
        (save_string): Use xmalloc, not malloc.
        (translate_name): Use a writable temporary variable to create and
        modify a string before setting it to a const char*.
        * prefix.h: New file to prototype functions exported from prefix.c.
