Fining Configuration Files

I've got some more Automake fun if anyone's feels like helping. I've
been up and down the info pages, and I can't find find an answer I like.
Suppose I have a program called foo. This program has a configuration
file in the etc directory called foo.conf. How do I make my program
aware of the location of this file?
The only workable solution I've been able to find is to add something
like this to my Makefile.in:
INCLUDES = -DCONF_FILE=\"$(etcdir)/foo.conf\"
....but that looks like a bit of a kludge to me. Can anyone suggest a
better option?
I think it would be best if there were some way to define the macro in
my config.h file, but I don't know if that can be done.
Anyway, thanks in advance for the help (again).

You should be using sysconfdir, and it should be specified via. -D
in the Makefile.am the rationale is found in info autoconf
Setup/Makefile Substitutions/Installation Directory Variables,:
"""\
Most of these variables have values that rely on `prefix' or
`exec_prefix'. It is deliberate that the directory output variables
keep them unexpanded: typically `@datadir@' will be replaced by
`${prefix}/share', not `/usr/local/share'.
This behavior is mandated by the GNU coding standards, so that when
the user runs:
`make'
she can still specify a different prefix from the one specified to
`configure', in which case, if needed, the package shall hard code
dependencies corresponding to the make-specified prefix.
`make install'
she can specify a different installation location, in which case
the package _must_ still depend on the location which was compiled
in [...]
In order to support these features, it is essential that `datadir'
remains being defined as `${prefix}/share' to depend upon the current
value of `prefix'.
....
