24 * i386/bsd.h (ASM_FILE_START): Don't use dump_base_name, it is
25 wrong and should only be used for dump related things, not

63 1998-12-07 Zack Weinberg <zack@rabi.phys.columbia.edu>

68 (cpp_reader_init): Call initialize_char_syntax with no
70 (cpp_start_read): Don't call initialize_char_syntax again.
71 Clear is_idchar['$'] and is_idstart['$'] if not

112 hardcoded MASK, which is safe since this is the source
115 * cppexp.c: Bring over changes to cpp_parse_escape from cccp.c
116 to handle wide character constants in #if directives. The
117 function now returns a HOST_WIDE_INT, and takes a third
118 argument which is a binary mask for all legal values (0x00ff
119 for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.) Define
120 MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK. Change callers of
