This problem is due to a libtool bug which I have reported to the
libtool mailing list.  It could perhaps be worked around by providing
a C++ language version of gm (e.g. gm.cc) in the case where libfpx is
found.

Libfpx is known to work properly under SPARC Solaris and Windows.  It
fails in strange ways under Linux and FreeBSD.  Perhaps one reason for
the Linux/FreeBSD linkage problem is due to using the C compiler to do
the link rather than C++.

Hmmm, I will take a look at that.  I have done some work to try to
make libfpx "appear" portable, but since it wasn't written portably
from the start (and uses legacy C++ rather than modern C++) there are
still hidden portability problems which require a dedicated maintainer
to resolve.
