When using automatic dependencies, if you include an old dependencies file that
have a file that was removed, make will issue an error like:
make: *** No rule to make target `missing_file.d', needed by `some_rule'.
Stop.
To avoid this there is a popular trick used by GCC consisting in adding empty
rules for each source file. Make treats any empty rule (no prerequisites, no
actions) as if they were .PHONY (and not issuing any errors), so the effect of
doing this is, if a file that was listed as a dependency is gone, a rebuild
will be triggered.
rdmd should do the same.
