7790 * i386/bsd.h (ASM_FILE_START): Don't use dump_base_name, it is
7791 wrong and should only be used for dump related things, not

7885 for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.) Define
7886 MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK. Change callers of

8692 The strategy we now use is to pre allocate the top_elt along
8693 with the EH context so that each thread has its own top_elt.
8694 This is necessary as the dynamic cleanup chain is used on the
8695 top element of the stack and each thread MUST have its own.
