I have only tried XP/SP3 myself (where everything works), but Vista might 
be the problem.

Since there is a strange CR (\r) showing up here, the problem might also 
stem from DOS style CRLF conversion.  When installing Cygwin there is a 
global option to enable this; the (RECOMMENDED) default is plain 
Unix/binary mode whithout implicit conversion.

In general Isabelle expects proper Posix semantics for all basic system 
operations.  Cygwin is surprisingly good at this, turning alien windows 
into a solid Posix environment (sometimes even better than Mac OS).
