Looking at it a little more closely, it looks like pthread.h was written for Cygwin,
and unconditionally defines all the pthread related types and functions, but is now
depending on sys/features.h to set the _POSIX_* macros.
sys/types.h also defines defferent versions of these same types but only for
__rtems__and sys/features.h does define the _POSIX_* macros, but also only for
