I plan to work on adding OpenCL support to the build
system soon after the OpenMP support is done.


the last missing piece for the OpenMP stuff is to
add a test compile to configure.in which does
  $(CC) $(OMPCFLAGS)
to check if the named compiler really has OpenMP
support built in.  (e.g. for gcc test if `gcc -fopenmp`
works, as that only exists for gcc versions >=
4.2.1)

it should be trivial but I'm no autoconf expert.

I see that Autoconf has a AC_OPENMP macro, but don't
know if that applies to version 2.13. I'm guessing
that it doesn't.
