I don't see how the patch could do that, unless sigprocmask.c
includes pthread.h somehow.  Can you verify whether that happens,
by using gcc -E?  If so, which file is the immediate includer
of pthread.h?  And if not, what's the difference beween
the output of gcc -E sigprocmask.c, with and without the patch?

Also, could you please try the simpler patch here instead?
