Q: Does the GNU compiler source code (provided by NeXT as product #N5514) include the Objective-C run-time library? If not, what good is the compiler without it?\
\
A: The Objective-C run-time library on the NeXT software release was developed at NeXT and is proprietary software. Source code for this library isn't included with the compiler source, nor is NeXT obligated to provide it.\
\
However, you can link against NeXT's run-time library. This gives you your own customizable, fully functioning Objective-C environment, letting you:\
The Free Software Foundation is working on their own Objective-C run-time system, to be available as source code in GNU 2.0. This should make it relatively easy to port the Objective-C environment to another platform.\
