Timo,

Please send the output from the following command for all three of the
symbols that are undefined:

c++filtppc _Z7WireSetIsEvRKT.

This "demangles" the c++ symbol. Hopefully, we can determine which of the
overloaded functions are undefined.

A complete rebuild of base, and the application, might also help. Also, make
certain that the same c++ compiler version is used to produce all of the
object code linked into mv3100.munch.

Jeff
