Heredocs are not the problem here but the <() process substitution.
It opens a descriptor to a pipe, which has (faked) permissions 0666
on Cygwin.  Pipes on Linux have 0600 permissions.  Since pipes on
Cygwin are also created with r/w permissions for the user only, I
changed the mode bits returned from stat/fstat for pipes accordingly
in CVS.
