Thanks!

Hmmm... I'm sorry, but I just realized something potentially problematic. I seriously doubt that it actually is problematic, but I feel obligated to note it:

I put the line inside of the same #ifdef block that the existing #include <pthread_np.h> was in. That's fine for my machine, which is running FreeBSD, but the block also applies to OpenBSD.

Looking at OpenBSD's source for phtread_np.h and pthread.h, it seems to me like this change is almost certainly not needed for modern OpenBSD, as their phtread_np.h itself has a #include for pthread.h. On the other hand it shouldn't hurt, as pthread.h has a standard #ifndef/#define guard in place.

Plus that #include <pthread.h> has been there for five years, so I guess this change might help if for some reason someone wants to run FrankenPHP on some ancient, unsupported version of OpenBSD ¯\_(ツ)_/¯

But strictly speaking, I don't know if it's OK or not. I haven't tested it on OpenBSD (which I've never installed anywhere, and which as far as I can remember I've never knowingly used at all ever in my life).

I am trying to package this for arch linux and ran into this same issue, can we just include it generally?

@travisghansen yes, I guess it won't hurt. Would you mind to open a PR?

@dunglas sorry for the delay, yes I can but I may just use the prebuilt binaries (although that is less than ideal). I was getting errors about hitting max stack size (iirc). Are there specific build args I should be using to match what you do?
