A quick update: Scheme built this way isn't fully functional. DISK-SAVE / DISK-RESTORE fail, for example: saved bands cannot be reloaded. I really have no idea what's going on. But it is working well enough for what I need it for.
FYI, I also ran the tests (with FAST=y), and the following tests failed: FAILED: "runtime/test-library-ixports" FAILED: "runtime/test-syncproc" FAILED: "ffi/test-ffi" Happy to share more details if anyone is interested. Cheers, Kevin
