    Hi Ernest,


  You progably stil have -nostdlib in your build flags somewhere.  You
need to link with libgcc.a, which would be done automatically without
that flag.  Alternatively if you aren't actually using the C++ exception
system, you can save a whole load of executable file size and runtime
overhead by specifying -fno-exceptions.

   cheers,
     DaveK
