7753 * i386/bsd.h (ASM_FILE_START): Don't use dump_base_name, it is
7754 wrong and should only be used for dump related things, not
7755 debugging information, instead main_input_filename should be used.
7756 Also, reuse output_file_directive if possible.
7757 * i386/aix386ng.h (ASM_FILE_START): Likewise.

7796 identifier character. Take no arguments.
7797 (cpp_reader_init): Call initialize_char_syntax with no
7799 (cpp_start_read): Don't call initialize_char_syntax again.

7801 opts->dollars_in_ident.
7803 * cpplib.h (struct cpp_reader): Replace void *data element by

7841 hardcoded MASK, which is safe since this is the source
7844 * cppexp.c: Bring over changes to cpp_parse_escape from cccp.c
7845 to handle wide character constants in #if directives. The
7846 function now returns a HOST_WIDE_INT, and takes a third
7847 argument which is a binary mask for all legal values (0x00ff
7848 for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.) Define
7849 MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK. Change callers of
7850 cpp_parse_escape to match. [Fixes c-torture/execute/widechar-1.c]

8655 The strategy we now use is to pre allocate the top_elt along
8656 with the EH context so that each thread has its own top_elt.
8657 This is necessary as the dynamic cleanup chain is used on the
8658 top element of the stack and each thread MUST have its own.
