--- Comment #2 from th.r.klein at web dot de 2011-02-22 19:39:27 UTC --- For example a microcontroller do not need to have any kind of standard C-Library files or its header files. So it is not possible to build e.g. zlib or libiberty for this target platforms. Additional I might to take a decision not to build this library, even if it is possible to build it. The build process failed here.
