We use the following rule along with an include for many of the OSS
programs we maintain:

     makedepend -Y [local include flags] -f Dependencies [source files]

This generates a (separate) dependency file for all of the named
source files, and omits the standard include directories (so you
only get local dependencies).  We then distribute the generated
dependency files in case the end-user doesn't have "makedepend"
(or the equivalent compiler program + options) on their system.

For Ghostscript you could use something like "filename.dep" for
dependencies used by "filename.mak".
