Since somebody suggested that _REENTRANT is defined on HP when the '-mt' 
flag is used, what about only adding adding following to this #if

  #     if defined(_POSIX_THREAD_SAFE_FUNCTIONS) \
        && defined(_SC_THREAD_SAFE_FUNCTIONS) \
        && (_POSIX_THREAD_SAFE_FUNCTIONS+0 >= 0)
        || (defined(__HP_aCC) && defined(_REENTRANT))
