Actually, this function only works if the user has the default cygdrive
prefix.  This can and often *is* changed, however.  Fortunately, the
Cygwin developers have had your back on this for a very long time.  Use
the cygpath program to convert all your paths.  It safely handles
conversions both to and from POSIX for both absolute and relative paths,
can convert to short form DOS paths (e.g C:\Progra~1\...), supports
paths with arbitrary whitespace, can provide many well known paths such
as the user's Desktop directory, can be run by Windows-native programs,
and more.
