The condition variable stuff is part of 1003.1c-1995, yes.  I assume 
that's what you mean by POSIX 95.  You should be able to just apply the 
same changes to gthr-posix95.h.

Not a big deal, but you should be able to just use 
wait_recursive(static_mutex) here.  Whichever you prefer.

The patch is OK with the update to gthr-posix95.h; I imagine Eric will 
let you know if it breaks for some reason.
