I fear the respondent didn't understand your question, or didn't read
the whole thing.  AC_ARG_WITH is the macro used to define a specific
value of 'foo' that *should* be processed by autoconf.  We certainly
aren't going to call AC_ARG_WITH for all possible values of 'foo' just 
to get it to ignore the ones that aren't used...
