Comment:

 OK, this looks sorted.

 We had established there is no need to force any particular compiler, and
 the problem was with the new linker.

 Mark elegantly determined that it was "flat-namespace" that was the
 killer, and that because we set MACOSX_DEPLOYMENT_TARGET in MacPorts, that
 flat namespace is not going to be added to our macports builds.

 I can certainly confirm that there is no "flat namespace" in the macports
 builds:

 {{{
 /bin/sh ../libtool  --tag=CC   --mode=link clang  -O2 -pedantic -fomit-
 frame-pointer -m64 -mtune=nehalem -march=nehalem -no-install  -o
 libtests.la  memory.lo misc.lo refmpf.lo refmpn.lo refmpq.lo refmpz.lo
 spinner.lo trace.lo amd64call.lo amd64check.lo ../libgmp.la
 }}}

 and upstream has updated libtool already so that users playing with this
 outside of macports should see their "make check" working right with the
 next release.

 Case closed!

 Of the closing options -- the only one that really fits is "invalid" as
 this never affected macports builds anyway, in the end.

 If someone doesn't like "invalid", feel free to reclose it with whatever
 you want.
