Ah RIGHT -- *that* was the reason: AC_CONFIG_FILES. This is why I asked before I committed. :-)

Ok. I'll do something here; I think the right solution is to:

- have valgrind AC_MSG_WARN instead of AC_MSG_ERROR (which I committed already)
- have the memchecker/configure.m4 error if you --enable-memchecker but then no components are available to be compiled

The latter is important because this is a static-only framework (i.e., a new component can't be introduced at run-tmie via DSO).

Cool. I'll commit just that part tonight.
