[cl-debian] Vhanges in bit-bash.lisp

[R. Mattes]

Hello list(s),

between version 1.17 and 1.18 of the file src/code/bit-bash.lisp the
functions copy-to-system-area et al. got removed. Since these functions 
are used in some libraries distributed as Debian (source) packages i'd
like to ask for some advice on how to hide these chages. Ideally these
libraries should run both under sbcl 0.8.n as well as sbcl 0.9.n. What
would be the preferred way to detect the availability of these functions?
BTW, is there a place in the sources where such changes are documented
(something like a ChangeLog)? Upgrading my systems without knowing a
priory where to expect problems sometimes quickly degrades into
trial-and-error ... :-) There seem to be changes/deprecations listed in
the NEWS file. Is this the place to check (if so, maybe someone should
add the bit-bash changes to the NEWS file).

 Thanks for all the work
