No, I wasn't aware of that.

-stable thread apps need to be compiled with -D_THREAD_SAFE to get a
thread-safe errno. -current does not require that.

Linking both -current and -stable uses -pthread to get the right libraries
because people don't seem to be able to use -nostdlib.

I'm going to try building MySQL on -current this morning.
