The low level make runs a configure script, which
uses a "here document", like so
cat >outfile <<EOF
stuff
stuf
EOF
The outfile is empty after the above command is done.
(note: the low level make is just compiling the standard gnu "patch" source,
there is nothing special about this target)
Unfortunately I have not come up with a minimin test case yet, sorry.
The dos shell workaround do work, however.
