+# The "--Wl,--export-dynamic" flags are here to help people
+# experimenting with callbacks from C to SBCL, by allowing linkage to
+# SBCL src/runtime/*.c symbols from C. Work on this is good, but it's
+# definitely bleeding edge and not particularly stable. In particular,
+# not only are the workarounds for the GC relocating Lisp code and
+# data unstable, but even the basic calling convention might end up
+# being unstable. Unless you want to do some masochistic maintenance
+# work when new releases of SBCL come out, please don't try to build
+# real code on this until a coherent stable interface has been added.
+# (You *are* encouraged to design and implement a coherent stable
+# interface, though.:-| As far as I (WHN 2002-05-19) know, no one is
+# working on one and it would be a nice thing to have.)
