           Summary: Missing -Wc++98-compat-extra-semi warning in a class
                    definition

Hi, all.

This code, test.cc, Clang gives the right -Wc++98-compat-extra-semi warning in
a normal function defintion but misses the warning in function defined inside a
class definition.

$cat test.cc
void foo () { }; //warning
template  <typename> void foo() {}; //warning
class A {
    void foo () { }; //no warning
    template  <typename> void foo() {}; //no warning
};

$clang++ -c -Wc++98-compat-extra-semi test.cc
test.cc:1:16: warning: extra ';' outside of a function is incompatible with
C++98 [-Wc++98-compat-extra-semi]
void foo () { }; //warning
               ^
test.cc:2:35: warning: extra ';' outside of a function is incompatible with
C++98 [-Wc++98-compat-extra-semi]
template  <typename> void foo() {}; //warning
                                  ^
2 warnings generated.

I guess Clang should treats the same with above four lines. Is clang dealing
with this code for intentionally?

Every version from clang 7.0 to trunk behaves the same.


Thanks,
Haoxin
