The problem was in the Makefile, in that it did not have the following
compile def's:

-DVSIP_IMPL_PAR_SERVICE=0
-DVSIP_IMPL_HAVE_CVSIP=1
-DVSIP_IMPL_CVSIP_HAVE_FLOAT=1
-DVSIP_IMPL_CVSIP_HAVE_DOUBLE=1
-DVSIP_IMPL_CVSIP_FFT=1
-DVSIP_IMPL_FFT_USE_FLOAT=1
-DVSIP_IMPL_FFT_USE_DOUBLE=1
-DVSIP_IMPL_FFT_USE_LONG_DOUBLE=1
-DVSIP_IMPL_PROVIDE_FFT_FLOAT=1
-DVSIP_IMPL_PROVIDE_FFT_DOUBLE=1
-DVSIP_IMPL_PROVIDE_FFT_LONG_DOUBLE=0

They were in the GNUmakefile produced by the configuration script. I
would have expected these to be in acconfig.hpp. For our port to MinGW,
I manually put them in acconfig.hpp so application Makefiles/build
scripts don't have to define them.

Another problem was discovered if we include windows.h before the
vsipl++ include files. This file is part of the MinGW distribution and
is the main header for the Win32 API. Some other file that windows.h
includes confuses some of the vsipl++ template instantiations. I didn't
track down who the culprit was, but defining WIN32_LEAN_AND_MEAN is a
work-around. Otherwise an application has to make sure all relevant
vsipl++ .hpp files are brought in before windows.h.

That seems to be it, though. The reference implementation tests now work
in our MinGW environment.
