systems. See <http://savannah.gnu.org/patch/?7921> for further details.
The new macro AX_LIB_EV has been added, which checks for libev in a
pkg-config-like manner. The purpose of the macro is to unifty behaviour

recognizes more recent versions of the Python interpreter, too. See

The GNU Autoconf Archive is a collection of many macros for `GNU
Autoconf that have been contributed as free software by friendly
supporters of the cause from all over the Internet. Every single
one of those macros can be re-used without imposing any restrictions
whatsoever on the licensing of the generated `configure` script.
In particular, it is possible to use all those macros in `configure`
scripts that are meant for non-free software.
