That sounds like a nice thing to add. Thanks. One quibble:

This sort of macro will cause warnings with GCC and other compilers
if you use it in a context like this:
if (foo)
gl_tls_key_init (name, destructor);
because the compiler will warn about possible if-then-else nesting
problems. The usual do { ... } while (0) construct avoids this
problem.
