-m32 or -m64 unconditionally passed to cc

[R. Matthew Emerson]

cffi-grovel::*cpu-word-size-flags* is always set to either ("-m32") or ("-m64").

Not all compiler versions accept these flags. For instance, gcc on ARM does not accept -m32 (or -m64, for that matter).

I see that there's a "FIXME" here; unfortunately, I don't have any really great suggestions on how to detect what flags are appropriate.

Well, I suppose we can at least handle ARM specifically. Does setting *CPU-WORD-SIZE-FLAGS* to NIL on ARM work as expected? Also, does ARM support running 32-bit binaries on a 64-bit CPU?

Yes.

ARM is 32-bit only.

What does CCL push to features? Is it :ARM?
