Sorry. I'll try again.
I have already started to work around this issue but here is what I wanted.

First question:
* Does make allow functions in the list of prerequisites?

What I am trying to do:
* I have scripts that auto-generate dependency makefiles for files of a 
single suffix / file type.
Each file type has a script that knows how to parse the source files and 
determine dependencies within the sources.
For example, source files ending in: '.xms' might be parsed by the command:
/path/to/scripts/xms.mkdepend

I want to name these auto-generated dependency makefiles in relation to the 
source filenames.
I want my dependency files named in the form $(sourceFileName).mk
(I do not like the convention %.c has dependency file %.d since this loses 
trace of the relationship between %.c and %.d)

In this example, source file 'foo.xms' will have a related dependency 
makefile 'foo.xms.mk'

The problem is that I want the pattern rule that builds %.xms.mk have the 
tool 'xms.mkdepend' as a prerequisite

I will have many different source file types using the same naming 
conventions so I want one pattern rule to handle all.
Thus I was trying to write something like the following that would match 
foo.xms.mk target and exctract the middle part 'xms':

%.mk : % $(someMakeFunctionThatWillGenerateTheMiddlePart)

Here is an explicit rule for what I want:
foo.xms.mk : foo.xms /path/to/scripts/xms.mkdepend

Is there a way to generalize the above rule for all %.mk files?

I am working around this by including makefiles with explicit rules for 
each source file type.
