OK!  As you may have noticed, version 3 of my patch avoids COMMON
on all platforms where ONE_ONLY is available.
I can't help but wonder if this results in larger .o files (ls -l type sizes), or slower compiles... and how big of an effect it is.
Slower compile, I can't think of any reason to wonder that. Larger .o files... Conceivably it could increase or decrease the size of the .o files, but the effect is almost certainly negligible. The compiler currently uses COMMON for C++ vague linkage only in a few pretty rare cases.

Ah, sorry, I was thinking of the change that did this by default for all languages (including C), as C has the same problem that C++ does on darwin about dylibs and common, not your change.
