Contrary to Microsoft propaganda that says this feature was modeled
identical to Unix, Vista still does not support true symlinks.  Their
current implementation suffers from:
   - being limited to a max of 31 symlinks per directory.
   - relative symlinks cannot cross volumes.
   - mklink forces you to distinguish between a file or directory.
   - other pre-vista windows versions on a network cannot see the
symlinks (unlike Samba).
   - NTFS only, not available on FAT.

RUBY_PLATFORM =~ /win/

further check on OS version requires platform specific code or
checking the version of cmd.exe or similar.  Sys::Admin may give you a
more friendly way to do this.
