546 * i386/bsd.h (ASM_FILE_START): Don't use dump_base_name, it is

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

641 for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.) Define
642 MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK. Change callers of
643 cpp_parse_escape to match. [Fixes c-torture/execute/widechar-1.c]

1448 The strategy we now use is to pre allocate the top_elt along
1449 with the EH context so that each thread has its own top_elt.
1450 This is necessary as the dynmanic cleanup chain is used on the
1451 top element of the stack and each thread MUST have its own.
