Indeed, very strange.  Odd that it took them 4 years to release 3.81  
with that fixed.

That works, but ugly and doesn't cover the future is probably not  
what we want to do. (I saw some .1 versions in the make downloads)

I'd be happy with the unconditional pipe and recommending to  
developers to upgrade their make and not worrying about the 1-shot  
user builds.

Markus: have you been following this?  What's your make version, and  
does your linux package manager have a new version?  Or is it  
otherwise easily updated?

I wonder what version other linux distros are at?
