7822 for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.) Define
7823 MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK. Change callers of
7824 cpp_parse_escape to match. [Fixes c-torture/execute/widechar-1.c]

8629 The strategy we now use is to pre allocate the top_elt along
8630 with the EH context so that each thread has its own top_elt.
8631 This is necessary as the dynamic cleanup chain is used on the
8632 top element of the stack and each thread MUST have its own.

14795 (EXTRA_CONSTRAINT): Document more accurately, remove Q case as it
14797 (GO_IF_LEGITIMATE_ADDRESS): Allow TFmode for LO_SUM on v9 since fp
