This is interesting but it's not going to be easy to convert it to
Windows x64 because it uses several features that are not available
and not easy to provide.
First it uses inline assember code, which is not available in Windows
x64.
Secondly it uses long doubles via the x87 coprocessor, which won't be
easy to use from Windows and will, I think, need assembler support for
access in x64 mode.
