This a bugfix release for the second update to the second major release of

other Objective-C programs.
Highlights of this release include:

Various improvements for building and using libobjc2 on MinGW.
Improved support for the PowerPC architecture.
A fix for the detection of the tls-robin-map dependency.

You may obtain the code for this release from git and use the 2.2.1 branch:

The runtime library is responsible for implementing the core features of the

object model, as well as exposing introspection features to the user.  The

GNUstep runtime implements a superset of Apple's Objective-C Runtime APIs.
