Log message:
        Don't AC_SUBST too much, as it makes Automake include those
        variables in Makefiles, and drives autoscan to require unneeded
        programs.
        * acgeneral.m4 (_AC_INIT_PREPARE): Don't AC_SUBST CFLAGS,
        CPPFLAGS, CXXFLAGS and LDFLAGS.
        (AC_ARG_VAR): AC_SUBST the var.
        Document it only once, even if there are several different docs.
        * aclang.m4 (AC_PROG_CPP): Declare CPP and CPPFLAGS to AC_ARG_VAR.
        (AC_PROG_CXXCPP): Declare CXXCPP and CPPFLAGS.
