Having things in libstdc++ etc. using GMP runs into the same issues as 
libquadmath of not wanting to link in non-libc LGPL code unless required - 
in particular for -static-libstdc++, where you should be able to 
distribute a binary built with -static-libstdc++ without either it having 
a dependency on GMP (unless the relevant features are used) or including 
GMP code with the consequent complications to distribution requirements.  
(Quite apart from GMP changing its SONAME - not under our control, unlike 
libquadmath.)
