cpphash.h (U): New define, to correct type of string constants.
gcc:
* cpphash.h (U): New define, to correct type of string constants.
(ustrcmp, ustrncmp, ustrlen, uxstrdup, ustrchr): New wrapper
routines, to do casts when passing unsigned strings to libc.
* cppexp.c, cppfiles.c, cpphash.c, cppinit.c, cpplib.c: Use them.
* cppfiles.c (_cpp_execute_include): Make filename an U_CHAR *.
* cpphash.c (_cpp_quote_string): Make string an U_CHAR *.
* cppinit.c (dump_special_to_buffer): Make macro name an U_CHAR *.
* cpplex.c (parse_ifdef, parse_include, validate_else): Make
second argument an U_CHAR *.
* cppinit.c (builtin_array): Make name and value U_CHAR *, add
length field, clean up initializer.
(ISTABLE): Add __extension__ to designated-
initializers version.
* cpplex.c (CHARTAB): Likewise.
* mbchar.c: Add dummy external declaration to the !MULTIBYTE_CHARS
case so the file won't be empty.
include:
* symcat.h: Remove #endif label.
