rra-c-util 3.1

This release is mostly in support of pam-afs-session 2.1, which I'll be announcing next. It contains fixes for the embedded kafs layer for Mac OS X, a replacement for strndup if missing (which inexplicably Mac OS X doesn't have in its C library), and new capabilities in the pam-util library for vectors and list configuration parameters.

This release also has a few fixes to the Kerberos Autoconf probes and the beginnings of a license cleanup. Many more files are now in the public domain (or as close as one can legally get), using new language that originally came from IETF lawyers, and the Autoconf macros are under a more permissive license used by the FSF for many Autoconf macros. All files meant to be copied into another package now include explicit license statements.

You can get the latest version from the rra-c-util distribution page.
