I have a silly question, but...  is it really known for a fact that  
some Make out there do not support "include if it exists"?  The true  
problem is that this is handled by config.status instead of Make itself.

While at it, I have another portability question: are there (alive)  
shells known not to support () for case patterns?

case $host in
  (*win*) abort;;
  (*)     dance;;
