Thanks.
Do you think it's worth documenting this use case too?
I think the most common use would be for example:
AC_ARG_WITH(check,
AC_HELP_STRING([--with-check],[Use unit testing]),
[],[with_check=yes])
AC_LIB_HAVE_LINKFLAGS([check],[],[#include <check.h>],[void* t =
suite_create;])
echo "with_check = $with_check"
echo "HAVE_LIBCHECK = $HAVE_LIBCHECK"
