Dear all;

I don't know enough C++ to figure this one out--to me it seems the
compiler gets confused somewhere in the instantiation of some of the
templates in clipper_progs, at least on amd64 with gcc-4.3.4.  The
mystery error messages are:

  intensity_target.h:114: error: expected constructor, destructor, or
type conversion before ‘<’ token
  intensity_target.h:120: error: expected initializer before ‘<’ token

The attached patch works around whatever the problem may be by putting
the definition of the functions inside the class.

Also, it seems like the CCP4 people have modified the
ccp4-6.1.3-core-src tarball.  As a result, the manifests of
sci-chemistry/ccp4-apps, sci-chemistry/ccp4i, and sci-libs/ccp4-libs
need updating.

// Cheers; Johan
