- Upgrade to libmaa-1.4.2:
* Fix build failure on SunOS-5.11 (alloca)
* License has been changed from LGPL to MIT, permitted by Rik
Faith, original author of this library.
* Build system changed from autotools to mk-configure.
* Library version/soname was bumped from 3 to 4. I cannot
guarantee that mk-configure and libtool build shared library
the same way.
* Tests were added for stk_*, mem_* and prm_* functions.
* stk_isempty function was added.
* stk_* and other was reimplemented without obstack functions
(glibc extension).
