In that line:

               switch((st & htonl(0x00FF0000))) {
                       case htonl(0x00010000):

Perhaps it's a matter of includes again.

Thanks!

Grab the patch to that file from 2.5.41-ac and you'll be fine. Dave 'bigendian' Miller says its fixed in the main tree now

This is fixed in the current sources, just change the "htonl" to "__constant_htonl" in the case statements.
