6387 for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.) Define

7194 The strategy we now use is to pre allocate the top_elt along
7195 with the EH context so that each thread has its own top_elt.
7196 This is necessary as the dynmanic cleanup chain is used on the
7197 top element of the stack and each thread MUST have its own.
