This fixed the first error, but a second one appears:
In file included from ./signal.h:65,
from ./sys/select.h:84,
from /usr/include/sys/types.h:224,
from /usr/include/pthread.h:49,
from ./pthread.h:31,
from glthread/threadlib.c:28:

./pthread.h:252: error: expected ')' before '*' token

*** Error code 1
We have a circular loop of #includes:
<pthread.h> -> <sys/types.h> -> <sys/select.h> -> <signal.h> -> <pthread.h>.
This fixes it.

sys_select: Avoid syntax error on OpenBSD 5.0.
* lib/sys_select.in.h [OpenBSD]: When /usr/include/pthread.h is
currently being included, just include the system's <sys/select.h>.
