Unfortunately using runtime linking for pthreads causes problems. This has occurred for me when testing on FreeBSD. When
using runtime linking, deadlocks can occur (for me it happens when loading data from fread()). It turns out that doing
compile-time linking fixes this. I'm not sure why this happens, but the safest way I can think of to fix this is to simply
disable runtime linking by default. To enable runtime linking, #define this before the implementation of this file. I am
not officially supporting this, but I'm leaving it here in case it's useful for somebody, somewhere.
