[Bug c++/18724] New: missleading error message with undeclared template name

["belz at kolumbus dot fi" <gcc-bugzilla at gcc dot gnu dot org>]

std::list<int> foo();

$ g++ error.cpp
error.cpp:2: error: expected constructor, destructor, or type conversion before 
'<' token

This is missleading as mostly the case is that 'list' is just not declared.
I guess the issue should be handled similar to the case that the declaration 
would be in a function scope (when the error message is sane). However quick and 
not so good fix is also possible directly to parser (I experimented a bit and 
was able to have error message that is a bit clearer).

This particular error message have been after the new parser was introduced, the 
old error message was even worse.
