I don't think so; I'm seeing the same proliferation of dynamic linking 
symbols.  I guess I've never noticed the issue, because I normally use 
dynamic linking for these GCC prerequisite libraries.

FWIW, I built all of these libraries from unmodified upstream sources, 
using their build systems to generate both static and dynamic variants.  
Perhaps this is a bug in the MPFR build methodology, when building as a 
static library with both --enable-static and --enable-dynamic?  Or maybe 
a consequence of a bad design decision (IMO) by the GMP developers; they 
provide disparate (and incompatible) versions of include/gmp.h for each 
of the two configurations?  (FWIW, the gmp.h which we have distributed 
is from the '--enable-static --disable-shared' build).
