Based on feedback from a few people on #lisp IRC, I have merged a
slightly-adjusted version of this patch.  

There were two gotchas: one was that currently the feature :unix is
_on_ for Win32 builds; the second was that the UNIX-RELATIVE-PATHNAME?
function works for unix namestrings but does only what it says on the
tin, so was wrongly classifying Win32 pathnames.

Cheers,
