In Wien2k 14.2, the ‘w2waddsp’ section of x_lapw reads

case w2waddsp:
true >$def
…
if (! -s $file.amnup && ! -s $file.mmnup) then
  error "w2waddsp: neither mmn nor amn files present -- nothing to do"
endif
…

I later changed ‘! -s $file’ to ‘! ( -e $file.amnup && ! -z $file.amnup
)’ because older csh versions do not have the ‘-s’ test.  (Maybe it is a
‘tcsh’ vs. ‘csh’ issue.)

Does your csh support ‘-s’ (you can test that interactively)?  What does
‘csh --version’ say?
