33 # Generate compile-rules for the modules that we are using in libraries or
34 # programs.  We are listing them explicitly because we have turned off the
35 # suffix rules (to force compilation with the appropriate flags).  We could use
36 # make-recursion but that would result in makefiles that are useless for
37 # development.

44 #       crenames ("yes" or "no", flag to control whether -c & -o options are used)
45 #       cxxrenames ("yes" or "no", flag to control whether -c & -o options are used)
46 #       traces ("all" or "DEBUG", to control whether tracing is compiled in)
