1074 * i386/bsd.h (ASM_FILE_START): Don't use dump_base_name, it is
1075 wrong and should only be used for dump related things, not

1165 * cppexp.c: Bring over changes to cpp_parse_escape from cccp.c
1166 to handle wide character constants in #if directives. The
1167 function now returns a HOST_WIDE_INT, and takes a third
1168 argument which is a binary mask for all legal values (0x00ff
1169 for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.) Define
1170 MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK. Change callers of

1976 The strategy we now use is to pre allocate the top_elt along
1977 with the EH context so that each thread has its own top_elt.
1978 This is necessary as the dynmanic cleanup chain is used on the
1979 top element of the stack and each thread MUST have its own.
