> Is that also true for 32-bit?

I was testing the sse control word with 32-bit ucrtbase. It's not set in
msvcrt.dll from the game. I wonder how it works with msvcrt.dll from Windows 7
or 10 (I'll take a look tomorrow)?

I guess we might reimplement and call _CIasin in this case. Probably using sse
implementation will not be visible for most of the applications anyway (if we
decide to use the same code for msvcrt and ucrtbase).
