6312 * i386/bsd.h (ASM_FILE_START): Don't use dump_base_name, it is
6313 wrong and should only be used for dump related things, not
6314 debugging information, instead main_input_filename should be used.
6315 Also, reuse output_file_directive if possible.
6316 * i386/aix386ng.h (ASM_FILE_START): Likewise.

6355 identifier character. Take no arguments.
6356 (cpp_reader_init): Call initialize_char_syntax with no
6358 (cpp_start_read): Don't call initialize_char_syntax again.

6360 opts->dollars_in_ident.
6362 * cpplib.h (struct cpp_reader): Replace void *data element by
6363 cpp_options *opts. Rearrange elements to make gdb printout

6400 hardcoded MASK, which is safe since this is the source
6403 * cppexp.c: Bring over changes to cpp_parse_escape from cccp.c
6404 to handle wide character constants in #if directives. The
6405 function now returns a HOST_WIDE_INT, and takes a third
6406 argument which is a binary mask for all legal values (0x00ff
6407 for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.) Define
6408 MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK. Change callers of
6409 cpp_parse_escape to match. [Fixes c-torture/execute/widechar-1.c]

7214 The strategy we now use is to pre allocate the top_elt along
7215 with the EH context so that each thread has its own top_elt.
7216 This is necessary as the dynmanic cleanup chain is used on the
7217 top element of the stack and each thread MUST have its own.
