double hrm.  this was svn acting up on me again.  sometimes it fails to detect 
that a file actually has changes in it.  in this case, syscallent.sh wasnt 
fully committed.

now that i look at it again, i wonder what exactly the purpose of the END{} 
block in the awk is for.  it seems to completely pointless in my eyes.  why 
generate 100 extra syscalls that are known to be undefined ?
