 C     Flag used to indicate which flavour of multi-threading  
 C     compiler directives to use. Only set one of these.  
 C     USE_SOLARIS_THREADING  - Takes directives for SUN Workshop  
 C                              compiler.  
 C     USE_KAP_THREADING      - Takes directives for Kuck and  
 C                              Associates multi-threading compiler  
 C                              ( used on Digital platforms ).  
 C     USE_IRIX_THREADING     - Takes directives for SGI MIPS  
 C                              Pro Fortran compiler.  
 C     USE_EXEMPLAR_THREADING - Takes directives for HP SPP series  
 C                              compiler.  
 C     USE_C90_THREADING      - Takes directives for CRAY/SGI C90  
 C                              system F90 compiler.

 C--   Define the mapping for the _BARRIER macro  
 C     On some systems low-level hardware support can be accessed through  
 C     compiler directives here.  
 #define _BARRIER CALL BARRIER(myThid)  
   
 C--   Define the mapping for the BEGIN_CRIT() and  END_CRIT() macros.  
 C     On some systems we simply execute this section only using the  
 C     master thread i.e. its not really a critical section. We can  
 C     do this because we do not use critical sections in any critical  
 C     sections of our code!  
 #define _BEGIN_CRIT(a) _BEGIN_MASTER(a)  
 #define _END_CRIT(a)   _END_MASTER(a)  
   
 C--   Define the mapping for the BEGIN_MASTER_SECTION() and  
 C     END_MASTER_SECTION() macros. These are generally implemented by  
 C     simply choosing a particular thread to be "the master" and have  
 C     it alone execute the BEGIN_MASTER..., END_MASTER.. sections.
