IMHO, it *is* a bug.  It is not nice to rely on an assumption that
only compilers which produce native Unix code define `unix'.  DJGPP
shows that `unix' can be defined by a compiler which targets other
systems.

In general, it is best to test for a feature rather than for a name of
an operating system.  Perhaps that ifdef could be rewritten so that it
tests for the actual functionality?

Since the patch is for configure.in, the DJGPP version *must* be built
by running the configure script.

The DJGPP port of Autoconf usually takes care of other DOS-isms (such
as looking for executables with "test -x" instead of "test -f").
