6. Building non-core clients with SVR4

1. A lot of clients (even some which have explicit SVR4 support) require -DSYSV when building under SVR4. This will not be set when using the default configuration. A quick fix is to add something like the following to the client's Imakefile:

         #if SystemV4
              DEFINES = -DSYSV OTHER_CLIENT_DEPENDENT_DEFINES
         #endif
   

   The best solution is to modify the code so it compiles correctly without -DSYSV.
