Why? What's the effect/benefit?

AM_MISSING_PROG is not a documented automake macro. As such, it can
disappear from any automake release without prior notice. I wouldn't
want to use such a macro.

Strange. For gettext, I've listed the bison-built files only in BUILT_SOURCES,
not in EXTRA_DIST, and the distributions contain these files. How come that
this doesn't work for you? Which version of automake are you using? Have
you overridden the automake generated 'distdir' target?
