[r6rs-discuss] "Treatment of different versions"

Hi,

I don't understand the following sentence from Section 6.9 of the
R5.95RS rationale document:

  Windows DLLs are generally not versioned, and while Linux shared
  objects are versioned for linking, inter-object references do not
  designate a particular source object.

As I mentioned earlier on this list, the GNU linker supports symbol
versioning in a way that (i) allows a library to tell which version(s)
of a symbol it exports and (ii) allows a library/executable to tell
which version of a symbol it imports.

I like the idea of a rationale document (very helpful) and that of a
higher "release" rate. However, since formal comments are no longer
formally answered, it can be hard to follow the reasoning behind some
changes (or non-changes). This is particularly true of the decision to
keep library versioning and versioned base libraries in spite of the
arguments against it that were made on this list.

Thanks,
Ludovic.
