This is a bug in the FreeBSD header files: they are not
namespace-clean. The problem is a name clash between a macro `hp'
defined by the Mercury headers and a parameter name in the FreeBSD
header file. I suggest you report this as a bug to the developers of
the FreeBSD header files. I've attached a patch which will fix this.
