Not a real bump PR

We need to think about why after nearly a year Linux has no libnfs love, while Windows and everyone else already at version 1.6.1

This is a partial PR to maybe show the improvements that long overdue into making this jump. Current at 1.8.0

I realize more code is required into the compile and makefiles.

Please help with those guys where possible.

Thank you.
