Oh, indeed! Thanks for the observation and the fix. I have applied
it in your name. (The "tiny change" marker in the ChangeLog merely
means that the change is small enough that I could apply it without
asking you for a copyright assignment. Cf.
https://www.gnu.org/prep/maintain/html_node/Legally-Significant.html .)

The change was in gl_PTHREADLIB_BODY, not in gl_STDTHREADLIB_BODY.
But anyway, thanks for providing the change description in the
first place.
