Right, this effectively defines the default config
file location in the macro CONFIGFILE.

Since the dyn_CONFIGFILE variable is no longer a static
string but an allocated (char *), one can not simply
assign the value as in 3.0. You have to look at
the definition of the macro DEFINE_DYN_CONFIG_PARAM
to see where the default location comes from.
DEFINE_DYN_CONFIG_PARAM(CONFIGFILE) expands to this:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
static char *dyn_CONFIGFILE;

 const char *get_dyn_CONFIGFILE(void)
{
        if (dyn_CONFIGFILE == NULL) {
                return CONFIGFILE;
        }
        return dyn_CONFIGFILE;
}

 const char *set_dyn_CONFIGFILE(const char *newpath)
{
        if (dyn_##name) {
                SAFE_FREE(dyn_##name);
        }
        dyn_##name = SMB_STRDUP(newpath);
        return dyn_##name;
}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I.e., when set_dyn_CONFIGFILE() has not been
called yet, get_dyn_CONFIGFILE boils down to
"return CONFIGFILE;". That is, the constant
defined by the Makefile is returned.

Cheers, Michael
