No, it is not.  The reason the inclusion is conditional on Posix/XOpen
version is because the types declared in pthread_types.h constitute
namespace pollution according to the older standard, which did not describe
them.

Are you trying to build something that sets POSIX_C_SOURCE to a very small
value?
