1065 * i386/bsd.h (ASM_FILE_START): Don't use dump_base_name, it is
1066 wrong and should only be used for dump related things, not
1067 debugging information, instead main_input_filename should be used.

1153 hardcoded MASK, which is safe since this is the source
1156 * cppexp.c: Bring over changes to cpp_parse_escape from cccp.c
1157 to handle wide character constants in #if directives. The

1160 for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.) Define
1161 MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK. Change callers of

1967 The strategy we now use is to pre allocate the top_elt along
1968 with the EH context so that each thread has its own top_elt.
1969 This is necessary as the dynmanic cleanup chain is used on the
1970 top element of the stack and each thread MUST have its own.
