Fix to fileio.c to un-break W32 build

Fix to fileio.c to un-break W32 build

[Eric Hanchrow]

Building in Windows using MinGW suddenly broke -- Frename_file in
fileio.c calls the function Fmake_symbolic_link, but that function
isn't defined on Windows.  I think the right thing to do is simply
wrap the call in an `ifdef' like this, just as the definition of
Fmake_symbolic_link is:

A bit different fix checked in, please try again.
