OK, but an easy check whether I can safely link with the lib would be nice, too.

Another point of having a AC_CHECK_LTLIB - like macro would be a possibility to
check whether the version of the library is OK.
Sometimes it is not possible to use AC_CHECK_LIB to check whether a function is
in the library (due to calling convention).
Well, I just wonder what is the sense of the libtool's versioning system since
it can't be used by library users :-)
