cannot build on windows xattr not available

Hi. 
I tried to build emuman on windows, cause I like the idea of someone finally using hardlinks instead of having multiple copies of the same file.

I got error "could not find 'unix' in 'os'" when it came to xattr.
Apparently there is no xattr tool for windows.
Any chance to work around this, or having windows binary built some other way?

Thanks.
