Comment (by eschnett):

 Regarding "too many thorns": Please suggest another thorn into which to
 fold this test. All other thorns relate to certain features, and none
 subsume Cray pointers. We could conceivably merge test thorns, but I
 suggest to not make this a prerequisite for testing Cray pointers, as
 these are independent issues.

 Regarding autoconf: Autoconf support for Fortran is meagre. One can use
 Fortran 77 only, and this only because Cactus extends certain autoconf
 macros that otherwise support only C or C++. (We are using a very old
 version of autoconf.) I just checked, and running a Cray pointer test via
 autoconf is not trivial, as Fortran compiler flags seem to get lost.
 Testing the C/Fortran calling interface is also not possible from
 autoconf, since this is determined later (and basically outside autoconf).

 I believe this thorn has value as-is, if only to allow us get feedback
 about systems where Cray pointers don't work before we use them.
