Totally unrelated.  I use local.mk (should be local.am) because it’s
included from the top-level Makefile.am.  There’s a single Makefile
in the end, and that’s on purpose.  I do not want recursive Makefiles.

What example are you referring to?  Also, you may have noticed that
I try to avoid using the preprocessor in favor of Bison directives.

There’s no such thing in calc++-parser.  Be sure to read from the
build tree, not the source tree.

‘something’ is '%define api.value.type'.
