Yes, you've spotted the flaw  :-)
It would probably end up with three cases, the new initializer form
for posix-like gthr laters, the current assignment from temporary form
for e.g. gthr-single.h where the INIT macros expand to 0, and the
function call for when there's no INIT macro.

Probably not worth changing, since it only appears in two places.  Oh well.
