As long as you have target rules for all header files, which is
certainly the right thing to do, listing non-existing files should be
fine.

In any case, I suggest you to borrow CVS automake's dependency
generation mechanism, that works with a number of compilers and makes,
and generates dependencies as a side effect of compilation at the user
site.  Then, even when you have headers that are only included when
certain configure options are given, or machine-dependent headers, you
still get the correct dependency information.
