There is no way for a program to refer to the template constructor defined
in the class below. EDG eccp issues a warning to point this out, but gcc
silently accepts the code. It would be helpful if gcc were enhanced to
issue a similar diagnostic.
$ cat t.cpp && gcc -dumpversion && gcc -W -Wall -Wextra -pedantic -c t.cpp &&
eccp -c -v t.cpp
struct S { template <class> S () { } };

"t.cpp", line 1: warning: template parameter "<unnamed>" is not used in
declaring the parameter types of function template "S::S"
struct S { template <class> S () { } };
