/* Adding appropriate macros for the different POSIX units of
   functionality that PACE supports.
   These macros define which POSIX functions get included when
   PACE is built. The functions are grouped according to POSIX
   Units of Functionality per the POSIX document ?? pp. ??.
   The following macros correspond to the following POSIX
   Unit of Functionality:

   PACE_HAS_POSIX_SP_UOF       -> POSIX Single Process UoF
   PACE_HAS_POSIX_MP_UOF       -> POSIX Multiple Process UoF
   PACE_HAS_POSIX_SIG_UOF      -> POSIX Signals UoF
   PACE_HAS_POSIX_UG_UOF       -> POSIX User Groups UoF
   PACE_HAS_POSIX_FS_UOF       -> POSIX File System UoF
   PACE_HAS_POSIX_FA_UOF       -> POSIX File Attributes UoF
   PACE_HAS_POSIX_F_UOF        -> POSIX FIFO UoF
   PACE_HAS_POSIX_DI_UOF       -> POSIX Device I/O UoF
   PACE_HAS_POSIX_FM_UOF       -> POSIX File Descriptor Management UoF
   PACE_HAS_POSIX_P_UOF        -> POSIX Pipe UoF
   PACE_HAS_POSIX_DS_UOF       -> POSIX Device Specific UoF
   PACE_HAS_POSIX_SD_UOF       -> POSIX System Database UoF
   PACE_HAS_POSIX_CLS_UOF      -> POSIX C Language Support UoF
   PACE_HAS_POSIX_JC_UOF       -> POSIX Job Control UoF
   PACE_HAS_POSIX_UGR_UOF      -> POSIX User Groups (Reentrant) UoF
   PACE_HAS_POSIX_FL_UOF       -> POSIX File Locking UoF
   PACE_HAS_POSIX_CLSR_UOF     -> POSIX C Language Support (Reentrant) UoF
   PACE_HAS_POSIX_SDR_UOF      -> POSIX System Database (Reentrant) UoF
   PACE_HAS_POSIX_NONUOF_FUNCS -> Any POSIX function in PACE that is not in
                                  one of the above units of functionality.
