For platforms that support DOS filenames, "....:c:\temp:..." is interpreted
as one element in a search path list, but "...:c:/temp:..." is treated as
consisting of two, "c" and "/temp".

The GHC code goes further and probes the file system
to determine the interpretation of a path element that starts
with "<drive>:\" (or "<drive>:/"). With a little bit of effort, Hugs
could do the same.
