Does that mean the list can be empty?
void f() __attribute__((__abi_tag__()));
fails with "error: wrong number of arguments specified for ‘__abi_tag__’
attribute" while
inline namespace n __attribute__((__abi_tag__())) {}
is accepted by recent trunk GCC (as well as older versions).
That seems like a bug.
