Re: [BUG] lua 5.2 luai_hashnum bug with threads

[jpoag <James.Poag@...>]

So avoid frexp() altogether. Rollback to the 5.1 way of computing the hash.

I understand there's lot of history behind DirectX problems to the point of
"Well, if DX is involved, then it's not our fault"  or  "Our official
position is that ANSI-C doesn't recognize threading or DirectX, therefore it
doesn't exist."

I get it, I really do.  

But the truth of the matter is that the precision control can change out
from under Lua.  Lots of precision issues related to DirectX:
http://lua-users.org/cgi-bin/namazu.cgi?query=directx&idxname=lua-l&max=100&result=normal&sort=score

How hard is it to write a Guard macro that sets and restores the precision
control that evaluates to a no-op on non-windows platforms?
