Yeah, and this is tripping up gnu/dist/toolchain/libf2c. Really,
they're both wrong; the former because pthread_{sigmask,kill} didn't
exist in old versions of POSIX (9945-1:1996 is the first version where
it was in the main standard), and the latter (I think) because
pthread types arrived in sys/types.h before 1003.1-2001. Let me do
some more digging to find the right standard version to use in both of
them.
