 Interesting, I found GCC 4.1.2 working reasonably well for the VAX 
target, other versions are probably OK too -- why did OpenBSD stick to 
such an old version for that target?

 Anyway, I reckon GCC used to support long long even before that, although 
there might have been issues.

 FWIW, I concur.  I find them confusing and easy to avoid.
