Nicola Pero - June 3, 2011, 12:45 a.m.
This patch (second in the sequence of libobjc deprecated API removal patches) removes
the deprecated typedstream and archive functions, methods and types from libobjc.

Committed to trunk.

Thanks

PS: Tested on gnu/linux i686 by running both the ObjC/ObjC++ GCC testsuite, and the
GNUstep-base one.
