How about using AC_EGREP_HEADER to look for MCRYPT_API_VERSION and seeing what it is set to? 2.4 will be > 20000101 and 2.2 will be less. Of course, this doesn't account for future versions, but we've got no real way of knowing when this API change will occur ... -- Anil Madhavapeddy, <anil@recoil.org>
