+# The "--Wl,--export-dynamic" flags are here to help people

+# 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
