Compile with /fp:precise instead of /fp:fast in release mode on Windows

/fp:fast was introducing FP precision problems, and mixing it with some
/fp:precise code caused strange game behaviors, DSI exceptions and freezes.

This commit should fix most of the issues introduced by 3.0-73 (r95517a97).

Thanks to hatarumoroboshi@hotmail.com for tracking a lot of these Win32 bugs.

Fixes issue 4906.
Fixes issue 5138.
Probably fixes (not tested) issue 5067.
