3.3, 3.4 and mainline accept this piece of invalid code (note the 
missing 'const' on the signature in the explicit instantiation): 
-------------------- 
template <typename T> struct X 
{ 
    template <typename U> void foo (U) const {}; 
}; 
 
template void X<int>::foo (int); 
-------------------- 
 
On the other hand, 2.95 rejected this: 
g/x> /home/bangerth/bin/gcc-2*/bin/c++ -c x.cc 
x.cc:6: template-id `foo<>' for `X<int>::foo(int)' does not match any template 
declaration 
x.cc:6: confused by earlier errors, bailing out 
 
So this is a regression.
