Yo,
I naively had a go at fixing up IO's $#/$@ patch for 42-4 -
removing the lines:
if(msp+argc >= ems)
  {
    error("message stack overflow");
    goto broken;
  }

as suggested by
http://pure-data.svn.sourceforge.net/viewvc/pure-data/trunk/pd/src/m_binbuf.c?r1=8186&r2=9108
seems to do the trick - I've got a cleanly built 42-4 with $@ $# expansion.

Here's the modified patch, I'll put it in the patch tracker if there
are no complaints.
Best
Luke
