It would also be interesting to know if the --enable arguments are being generated correctly from this code fragment (should be obvious from configure --help output) because AC_FOREACH is a obsolete macro that's *supposed* to be just another name for m4_foreach_w ... except that it *might* be stripping a layer of quotes. zw
