Description Mattias Karlsson 2005-06-21 16:59:27 UTC 
Given:

void f(void)
{
   template<typename T> class A
   {
   };
}

g++ 4.0/3.4 gives: 
bug.cpp:4: error: expected primary-expression before 'template'

A better error message would be something like "Local template declarations is
not allowed" or something similar, instead of what is now basicly a "Syntax error"
Comment 1 Andrew Pinski 2005-06-21 17:04:16 UTC 
Confirmed, 3.3 and before gave a worse error message (at least to me):
t.cc:3: parse error before `template'
