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,
Stepan Kasal
