1081 * i386/bsd.h (ASM_FILE_START): Don't use dump_base_name, it is

1983 The strategy we now use is to pre allocate the top_elt along
1984 with the EH context so that each thread has its own top_elt.
1985 This is necessary as the dynmanic cleanup chain is used on the
1986 top element of the stack and each thread MUST have its own.
