Same with fresh SVN...

Some more info:

http://gcc.gnu.org/gcc-4.3/porting_to.html
--------8<--------
Explicit template specialization cannot have a storage class

Specializations of templates cannot explicitly specify a storage class, 
and have the same storage as the primary template. This is a change from 
previous behavior, based on the feedback and commentary as part of the 
ISO C++ Core Defect Report 605.

template<typename T>
   static void foo();

template<>
   static void foo<void>();

Gives:

error: explicit template specialization cannot have a storage class

This also happens with the extern specifier. Fixing this is easy: just 
remove any storage specifier on the specialization. Like so:

template<typename T>
   static void foo();

template<>
   void foo<void>();

and an example fix is here:
