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

1453 The strategy we now use is to pre allocate the top_elt along
1454 with the EH context so that each thread has its own top_elt.
1455 This is necessary as the dynmanic cleanup chain is used on the
1456 top element of the stack and each thread MUST have its own.
