<pre>Hi.
WebKit checks for the pthread_np include file using:
_HAVE_CHECK_INCLUDE(HAVE_PTHREAD_NP_H pthread_np.h)
However, on at least OpenBSD this will always fail because this file is not usable by itself.
It is usually used in conjunction with '<pthread.h>'.
Determining if the include file pthread_np.h exists failed with the following output:

ninja: build stopped: subcommand failed.
Previous versions did not have this issue because it was explicitely declared under Source/WTF/wtf/Platform.h:
#if (OS(FREEBSD) || OS(OPENBSD)) && !defined(__GLIBC__)
#define HAVE_PTHREAD_NP_H 1
#endif
I am not sure how (or even if) it is possible to add a dependent include to _HAVE_CHECK_INCLUDE.
Using autoconf, I'd do something like:
AC_CHECK_HEADERS([pthread_np.h],,,
[#ifdef HAVE_PTHREAD_H
#include <pthread.h.h>
#endif])
Thanks.</pre>
