I developed the cyclic buffer under MSVC 6.0 and g++ (I don't remember the
version). I tried to port it to MSVC 7, but I had some problems. Right now it has
no sense to put much effort to porting because I'm working on a new version with
"the iterator invalidation problem" fixed and in this version some of the "ifdefs"
will be removed.
