6308 * i386/bsd.h (ASM_FILE_START): Don't use dump_base_name, it is
6309 wrong and should only be used for dump related things, not

6351 identifier character. Take no arguments.
6352 (cpp_reader_init): Call initialize_char_syntax with no

6356 opts->dollars_in_ident.
6358 * cpplib.h (struct cpp_reader): Replace void *data element by

6399 * cppexp.c: Bring over changes to cpp_parse_escape from cccp.c
6400 to handle wide character constants in #if directives. The
6401 function now returns a HOST_WIDE_INT, and takes a third
6402 argument which is a binary mask for all legal values (0x00ff
6403 for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.) Define
6404 MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK. Change callers of
6405 cpp_parse_escape to match. [Fixes c-torture/execute/widechar-1.c]

7210 The strategy we now use is to pre allocate the top_elt along
7211 with the EH context so that each thread has its own top_elt.
7212 This is necessary as the dynmanic cleanup chain is used on the
7213 top element of the stack and each thread MUST have its own.
