Thank you very much.
I got it compiled after patching out the calls to  
rtems_bsdnet_initialize_tftp_filesystem() which does not exist anymore.

Next problem is a Null pointer derefence of symf.
The code path hits (in init.c)
     switch ( pathType(pathspec) ) {
         case LOCAL_PATH:
             fd = open(pathspec,O_RDONLY);
               if ( fd >= 0 )
                 symf = strdup(pathspec);

The open fails, and symf will not be set. Later, it is accessed and 
program dies.

I will investigate that further (should it open the file from a tftp 
mount? Maybe related to the problem above). For now I commented out the 
if line, so symf will get set anyway.

Next problem:
With tecla enabled, the shell spits out
   Cexp>Type '' for help (no quotes)
in an endless loop.
Without tecla, it seems to work.

That would be the next step. Any help is really appreciated.
