Estimated hours taken: 15 Split the automatically generated `.dep' file into two files. The new `.dv' file contains all the variable definitions which used to be in the `.dep' file, which now contains just the rules. With mmake including the `.dv' files before the user's Mmakefile and the `.dep' files after, this allows user-defined Mmakefiles to refer to the automatically-generated variables and automatically-generated rules to refer to variables defined in the user's Mmakefile. This was possible before to a limited extent, but in particular dependency lists for automatically-generated rules could not refer to user-defined variables. Also introduced `C2INITARGS' as part of an illustration of how this change is useful (though probably this should be a separate change). `C2INITARGS' should be used to specify extra files to be passed to `c2init', rather than the currently-used `C2INITFLAGS' (which should only be used for option flags). The `_init.c' target should depend on these extra arguments, but it was not possible to do this automatically prior to this change (at least, not if one wanted to support per-program specification of `C2INITARGS'). compiler/modules.m: Generate the new `.dv' files and revised `.dep' files. Update the `change_clean' and `real_clean' targets to delete the `.dv' files. Update the `_init.c' rule to refer to `$(ALL_C2INITARGS)' as well as `$(ALL_C2INITFLAGS)', and add a dependency on `$(ALL_C2INITARGS)'. scripts/Mmake.rules: Add appropriate rules and dependencies for `.dv' files. scripts/Mmake.vars.in: Add definitions for implementing `C2INITARGS'. scripts/mmake.in: Add code for using `.dv' files (while maintaining backward compatibility for when they don't exist). doc/user_guide.texi: Document the new `.dv' files. Document the new `C2INITARGS' variables and the dependencies they imply. ../clpr/Mmakefile: ../clpr/samples/Mmakefile: extras/complex_numbers/samples/Mmakefile: extras/complex_numbers/tests/Mmakefile: extras/graphics/mercury_opengl/Mmakefile: extras/references/samples/Mmakefile: extras/references/tests/Mmakefile: extras/trailed_update/samples/Mmakefile: extras/trailed_update/tests/Mmakefile: Update to use `C2INITARGS' instead of `C2INITFLAGS', where appropriate, and remove any now-obsolete `%_init.c' dependencies (which wouldn't have worked anyway since GNU Make ignores pattern dependencies with no commands).
