yes, ast.tmp is a problem, especially for threads
I know the s++ part is a problem too and requires an api redesign

before doing *any* patch I'd like to see side test timing/memory/etc results of
	current bad situation vs inline vs static function vs global function
for a loop that emulates mbchar(p)
the function forms would look something like

#define mbchar(p,wp)	(p+=_text_mbchar_fun(p,wp),*(wp))

where the caller provides the address of a wchar_t : &w
w == -1 would signal error and p would be advanced past the bad bytes

remember that somewhere a vector of locale-specific ast intercept functions needs to be accessed
I don't know how you escape the global var access problems there

anyway, I'm not going to communcate any more today until I get the alpha out
not enough hours ...
