When you use automake, you get all these nice user-controlled things
like --prefix and --sysconfdir (even if you don't want them).  I
generally advise to use them instead of working to not use them,
thereby confusing the user who might be running './configure --help'
and seeing that they exist and finding later that your packages is
working to ignore them.

You may find some additional interesting information here (automake
uses autoconf):

In short, assuming that the you are working
on controls the installation of the c/c++ compiled software that wants
to look for this configuration file, I would recommend against any stuff and instead do something like this in your

AM_CPPFLAGS = -DSYSCONFDIR=\"$(sysconfdir)"\

oops....I mean this:

AM_CPPFLAGS = -DSYSCONFDIR=\"$(sysconfdir)\"

This works because automake will supply you with a sysconfdir value
(either a default one, or one provided by the user).
