I wrapped the file that includes the above call XIntc_RegisterHandler(..)
but that did not help.
All files in lwip and the xilinx emac seem to have the 

#ifdef __cplusplus
 extern "C" { ...

around their headers.

The function is defined, when I use Ctrl+clicking onto XEmac_IntrHandlerFifo
the Platform Studio SDK points me to the function, which is located in
xemac.c. 
But the linker does not find it ...
