Re: MIT Scheme 11.1 fails to build because of Werror

[Lingyu Zhu]

I have the same issue:
Bad compiled-code version in FASL File: make.com
File has: compiled-code interface 3; architecture 14.
Expected: compiled-code interface 4; architecture 14.

My platform is Freebsd 12.2 (clang 10.0.1, mit-scheme 10.1.11), The
fallthrough warning was suppressed by manually edit CFLAGS defined in
Makefile.
Here is the microcode/config.log
