Comment (by kab@…):

 Replying to [comment:9 fhess]:
 > When SIG_ATOMIC_MAX is defined ... call_once does not work.  ... It
 seems the problem is due to uintmax_atomic_t being defined as a
 sig_atomic_t which turns out to be a signed rather than unsigned type.

 This problem with using sig_atomic_t has been reported separately:
 https://svn.boost.org/trac/boost/ticket/7499

 Too bad I didn't know about this sooner.
