Actually, I don't think the libtool docs explain DLL versioning on 
windows (the 'c - a' thing).  They DO explain about libtool's versioning 
scheme on UNIX, and if you read that and think about it hard enough you 
can synthesize the 'c - a' thing, and convince yourself that 'c - a' 
represents a "binary API compabitibility index" AND that DLLs on windows 
should be named USING that index, but it ain't obvious.

I posted an explanation of the 'c - a' thing -- in this very thread -- 
on Oct 12.
