Issue in gmpxx.h?

[Brian Gladman]

I have just had an email from a user of my GMP port asking me why line 
3181 of gmpxx.h reports:

gmp-4.1.4\gmpxx.h(3181) : error C2912: explicit specialization; 'void 
__gmp_set_expr(mpf_ptr,const mpf_class &)' is not a specialization of a 
function template

with VC++ 7.1.

I also noticed this some time ago but I could not see what might be 
happening.  Can anyone see what is causing this report?
