I have a Makefile.am with programs that are conditionally compiled, e.g.

I don't think you need to use EXTRA_PROGRAMS if you use the idiom
bin_PROGRAMS =
if ENABLE_STUFF
bin_PROGRAMS += foo bar
endif
EXTRA_PROGRAMS was designed for cases like
== in configure.ac ==
if test X; then
PROGS="foo bar"
else
PROGS="baz"
fi
AC_SUBST(PROGS)
== in Makefile.am ==
EXTRA_PROGRAMS=foo bar baz
bin_PROGRAMS=quux $(PROGS)
Without the EXTRA_PROGRAMS, automake wouldn't know what to do with things
like foo_SOURCES since foo is otherwise missing from Makefile.am.
