    The reason automake does conditionals is because some dinosaur makes don't. That said, if you really must do this, you could define your snippet as a variable in configure.ac and AC_SUBST it into your Makefile. That way, automake won't get a chance to see it. Remember to use AM_SUBST_NOTMAKE to avoid creating a line like FOO = @FOO@.)

    dnl In configure.ac:
    snippet='
    ifeq ($(somevar),Y)
    foo
    endif
    '
    AC_SUBST([snippet])
    AM_SUBST_NOTMAKE([snippet])
    

    and:

    ## In Makefile.am:
    @snippet@
    

    I sincerely hope there's a better way than this.
