Removed the following lines from m_compress:
                if (in->m_flags & M_EXT) {
#ifdef DEBUG
                        ASSERT(in->m_len == 0);
#endif
                }

since they do nothing unless DEBUG is set and if it is set the compile
falls over because ASSERT is only defined when the netiso code is
included. A more correct fix would probably be to wrap m_compress
with a ifdef NISO but m_compress is moved to the netiso directory in
4.4 anyway so simpler to just yank this bit of DEBUG code for 1.1.5
