1987 * i386/bsd.h (ASM_FILE_START): Don't use dump_base_name, it is
1988 wrong and should only be used for dump related things, not

2078 * cppexp.c: Bring over changes to cpp_parse_escape from cccp.c
2079 to handle wide character constants in #if directives. The
2080 function now returns a HOST_WIDE_INT, and takes a third

2082 for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.) Define
2083 MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK. Change callers of

2889 The strategy we now use is to pre allocate the top_elt along
2890 with the EH context so that each thread has its own top_elt.
2891 This is necessary as the dynmanic cleanup chain is used on the
2892 top element of the stack and each thread MUST have its own.
