Sorry to all Objective C users, I didn`t tested the contents of this
subdirectory since I`m not using Objective C. If someone encounters
some problems, please mail me and I hopefully will fix what I can.
I only tried to compile a .m file and it indeed worked :-)

During compilation of Objective C runtime, I found that it supposes
the 'char' type to be signed on all platforms, which is not true.
Moreover, pgcc/os2 *is* using unsigned char by default, so I compiled
the runtime with -fsigned-char, and maybe you will be forced to
use this switch too. If you have any objections/problems, please
contact me.
