1046 * cpplib.c (initialize_char_syntax): Use ISALPHA and ISALNUM
1047 so it'll work on non-ASCII platforms. Always consider $ an
1048 identifier character. Take no arguments.
1049 (cpp_reader_init): Call initialize_char_syntax with no
1051 (cpp_start_read): Don't call initialize_char_syntax again.
1052 Clear is_idchar['$'] and is_idstart['$'] if not
1053 opts->dollars_in_ident.
1055 * cpplib.h (struct cpp_reader): Replace void *data element by
1056 cpp_options *opts. Rearrange elements to make gdb printout
1057 less annoying (put buffer stack at end).
1058 (CPP_OPTIONS): Get rid of now-unnecessary cast.
1060 * cppmain.c: s/data/opts/ when initializing cpp_reader
1062 * c-decl.c: Likewise.

1073 the actual-directory chain.

1085 * cpplib.c (do_include): Don't allocate a file_name_list on
1086 the fly for current directory "" includes, use the one that's
1087 been preallocated in pfile->buffer->actual_dir. Hoist out
1088 duplicate code from the search_start selection logic.
1089 (cpp_reader_init): Initialize pfile->actual_dirs.
1091 Remove definition of HOST_WIDE_INT. Change calls
1092 to cpp_parse_escape to match changes in cppexp.c (note
1093 hardcoded MASK, which is safe since this is the source
1096 * cppexp.c: Bring over changes to cpp_parse_escape from cccp.c
1097 to handle wide character constants in #if directives. The
1098 function now returns a HOST_WIDE_INT, and takes a third
1099 argument which is a binary mask for all legal values (0x00ff
1100 for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.) Define
1101 MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK. Change callers of
1102 cpp_parse_escape to match. [Fixes c-torture/execute/widechar-1.c]

1907 The strategy we now use is to pre allocate the top_elt along
1908 with the EH context so that each thread has its own top_elt.
