The case variance is a red herring.  Also, Cygwin doesn't understand the
%...% notation.  OTOH, you're not supposed to be seeing these entries in
the actual value of your PATH, either in Windows or in Cygwin.  Such
entries are usually caused by the wrong type assigned to the PATH value in
the registry (REG_SZ instead of REG_EXPAND_SZ).  Some buggy installers
change the type of the PATH registry entry.  You need to change it back,
so that strings like %SystemRoot% will be automatically expanded by
Windows before Cygwin ever sees them.
HTH,
