If you do, then you should be aware that AC_DEFINE_DIR, which is not a standard autoconf builtin macro, (in spite of its apparent assignment to the AC namespace), depends on exactly the same undocumented autoconf internals as the solution I suggested earlier. As an example of the type of breakage I referred to then, the original formulation of AC_DEFINE_DIR broke when autoconf added `datarootdir', requiring an extra round of `eval' to resolve `$datadir', for example. This sort of definition is fragile, for precisely this reason; it will break again, if a future autoconf version chooses to add yet another level of indirection, for some definition you just happen to want to resolve, when you invoke its expansion in the configure script.
