<pre>Gcc accepts __attribute__((visibility("hidden"))) anywhere it accepts 'static.
So it accepts
int __attribute__((visibility("hidden"))) foo() {
}
but rejects
int* __attribute__((visibility("hidden"))) bar() {
}
clang accepts both (but agrees with gcc as to where 'static' can be).
Not sure if this is an intended extension or not, but it can cause problems in
codebases where clang is the main compiler but gcc is still supported (as with
clang itself).</pre>
