Apparently Windows (I'm a unix developer by trade, so I'm slightly out
of my depth) automatically uses the short form for TEMP directories to
be compatable with DOS batchfiles.  Some programs don't support using
these old-format paths...

The solution is apparently a win32 function (non-portable, you'll need
to check if your code is being compiled on windows) called
getLongPathName() [
http://msdn.microsoft.com/en-us/library/aa364980(VS.85).aspx ]
can be used to do the conversion.  Unfortunately, I don't know enough
about win32 to suggest a it's use beyond the documentation I linked.

Peace,
Gary
