Ah, ok, then the latter method may be better. If your FILE,PRIORITY,SHARE,COMMAND LINE arguments were from some finite set, you could transpose: --with-modules-using-file-ThisFile=foo,bar,baz --with-modules-using-prio-ThisPrio=foo,bar,baz but I assume that is not the case. > > or > > --with-foo-module --with-bar-module... > > The ``foo'', ``bar'' parts aren't preassigned, everything is possible. > Also the number of modules isn't limited (in theory). OK. There are a couple of issues you have to deal with then: First, configure --help output cannot list your allowed switches, but you may be able to either directly divert text to the HELP_WITH diversion, or use a bogus AC_ARG_WITH([--with-*-module]...) or so as a workaround. Second, you have to actually get at the switches that were used. I think you can proceed similarly to the algorithm used by _AC_CACHE_DUMP to enumerate all variables, then work from that; see the respective macros in autoconf/lib/autoconf/general.m4. Beware, this is tricky code, and full of portability pitfalls, too, if you have to cater to different shells. Third, with Autoconf 2.62 you will need to use AC_DISABLE_OPTION_CHECKING to avoid warnings about options not directly recognized by the configure script. Sorry I don't have a simpler solution.
