* cpphash.h (struct spec_nodes): Remove n__CHAR_UNSIGNED__.
* cpphash.c (_cpp_init_hashtable): Similarly. * cppinit.c (cpp_create_reader): Default the signed_char flag. (init_builtins): Define __CHAR_UNSIGNED__ appropriately. (COMMAND_LINE_OPTIONS): Recognise -f{un,}signed-char. (cpp_handle_option): Handle the new options. * cpplex.c (cpp_interpret_charconst): Use new flag. * cpplib.h (struct cpp_options): New member signed_char. * gcc.c (cpp_unique_options): Remove %c spec and documentation. (cpp_options): Handle -fsigned-char and -funsigned-char. (static_specs): Remove signed_char_spec. (do_spec1): Don't handle %c. * system.h: Poison SIGNED_CHAR_SPEC. * tradcif.y (yylex): Use flag_signed_char. * tradcpp.h (flag_signed_char): New. * tradcpp.c (flag_signed_char): New. (main): Handle new command-line options. (initialize_builtins): Define __CHAR_UNSIGNED__ if appropriate. config: * alpha/alpha.h (SIGNED_CHAR_SPEC): Remove. * avr/avr.h: Remove old comments. * i960/i960.h (CPP_SPEC): Pass -fsigned-char if -mic*. (CC1_SPEC): Pass -fsigned-char if -mic*. (SIGNED_CHAR_SPEC): Remove. doc: * tm.texi (SIGNED_CHAR_SPEC): Remove documentation. testsuite: * gcc.dg/cpp/uchar-1.c, uchar-2.c, uchar-3.c: New tests. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@49444 138bc75d-0d04-0410-961f-82ee72b054a4
