How to pack multiple statements

I'd like to regroup multiple statements in a []:

AC_ARG_WITH(
    [float],
    [AS_HELP_STRING(
        [--with-float],
        [use float instead of doubles to store polynoms coefficients])],
    [real=float], <--- here I'd like to add an AC_DEFINE
    [real=double])

My problem is, I'm not sure of the best way to do that. I guess I can use ;, but this does not seem really idiomatic for a m4sh script.

Use newlines:

AC_ARG_WITH(
    [float],
    [AS_HELP_STRING(
        [--with-float],
        [use float instead of doubles to store polynoms coefficients])],
    [real=float]
    [AC_DEFINE....],
    [real=double])

It's also common to write it as:

 AC_ARG_WITH([
        float
        ],[
        AS_HELP_STRING(
            [--with-float],
            [use float instead of doubles to store polynoms coefficients])
        ],[
        real=float
        AC_DEFINE....
        ],[
        real=double
])
