I've now found some information on porting to winsock, but it affects
quite a few things in 'parallel', so I can't fix this immediately. For
now, on MINGW 'parallel' should be configured with --disable-cluster
to avoid this problem.

Any further discussion on fixing this should go to the bug tracker,
where Tatsuro open a report for this.

This can happen for Makefile commands like:

ENV_VAR=$(ENV_VAR_VALUE) called_program ...

if the quotes around "$(ENV_VAR_VALUE)" have been forgotten and
$(ENV_VAR_VALUE) expands to more than one token. But there are
currently no such constructs in optim/src/Makefile.in or
struct/src/Makefile.in, so without further information I'd guess the
reason is in the cross building environment.
