7321 * i386/bsd.h (ASM_FILE_START): Don't use dump_base_name, it is
7322 wrong and should only be used for dump related things, not

8223 The strategy we now use is to pre allocate the top_elt along
8224 with the EH context so that each thread has its own top_elt.
8225 This is necessary as the dynamic cleanup chain is used on the
8226 top element of the stack and each thread MUST have its own.
