[Bug c++/25751] New: Poor error when templating on undefined types

["chris at bubblescope dot net" <gcc-bugzilla at gcc dot gnu dot org>]

#include <vector>

int main(void)
{
  std::vector<foo> v;
  v.begin();
}

Produces:

temp.cc: In function 'int main()':
temp.cc:5: error: 'foo' was not declared in this scope
temp.cc:5: error: template argument 1 is invalid
temp.cc:5: error: template argument 2 is invalid
temp.cc:5: error: invalid type in declaration before ';' token
temp.cc:6: error: request for member 'begin' in 'v', which is of non-class type
'int'

That last warning doesn't seem to make any sense. Perhaps g++ should abandon
parsing / producing errors earlier?
