The autoconf manual was just updated today to also document that using 
[] around range expressions is also a valid workaround.  The solution 
still is POSIX-compliant; it's just that you are transliterating [ and ] 
to themselves in a working tr.

I'd rather use a simple idiom (always use []) than a more complex idiom 
(play with PATH to find a more-compliant tr) when both are valid 
workarounds.
