Yes, it is currently not supported. I am not sure if there are serious
attempts to add it.

This is a bug in FreeOCL. The istream::get() function returns an
istream reference, which can't be cast directly to bool. However, there
is a negation operator defined for istream, so the line can be changed
to:
const bool ok = !!in.get(c);
I have attached a patch for the port as I have built it here with clang.
I didn't add the dependency on atomic_ops yet, but it should be fairly
trivial.
Note I also needed a fix for Mk/bsd.cmake.mk, otherwise the required
${CPPFLAGS} would not be passed along to CMake, and then the build would
still fail to find the atomic_ops headers in /usr/local/include.
