The gw6c package fails to compile for me on my ARM testbed. It fails to find a truckload of uClibc++ symbols (seems like it does not find any). The uClibc++ linker options seem to be present, however. I was unable to fix this properly.
The following patch removes the uClibc++ dependency. It compiles properly with this applied. However, does somebody have an idea why it is unable to find uClibc++ symbols?
