well, I wouldn't hesitate to use the above.

But if you don't like it, you can separate the declaration from
AC_DEFINE, using AH_TEMPLATE:

AH_TEMPLATE([HAVE_LIBREADLINE], [Define to 1 if you have the
        `readline' library (libreadline).]
...

Or you can use undocumented macro AH_CHECK_LIB:

AH_CHECK_LIB([readline])
AH_CHECK_LIB([check])
AH_CHECK_LIB([m])

Or, if you want to make in in one go for all three:

m4_foreach([A_LIB], [readline, check, m], [AH_CHECK_LIB(A_LIB)])

Hope this will help,
