GraphicsMagick adds a pthreads dependency by default so we have a lot of experience with this. It is good to be aware that libtool will then impact you by adding whatever option enables pthreads in the compiler to its installed .la file so the option is replayed when software depending on the library is compiled. Systems with multiple compilers might not all use the same options to enable pthreads and so you might hear some new complaints due to unexpected compilation failure of dependent software. I encounter this issue on Solaris between GCC and the Sun/Oracle C compiler. There do exist systems which have different threading modes and pthreads is one of several threading modes. SGI's defunct IRIX is a good example of this. It is possible (I am not completely sure) that the GO language implementation has a threading model which is funky with posix mutexes because it uses a multi-tier threading strategy mixing both green and native threading models. GO language code can link with C language libraries. By depending on pthreads one is hoping that the pthread mutex will work with whatever threading model is actually used (i.e. everything funnels down to a consisting locking implementation). This is a safe assumption on most systems.
