Well, changing the architecture did change something:

Creating constants file.
"/Volumes/Data/dev/mlton-trunk/build/bin/mlton" -target "self"
-build-constants true >tmp.c
unknown switch: -fno-common

The previous error was "invalid target: self" (corresponding to the
unrecognized self architecture x86_64).  The "-fno-common" string is
part of the "-cc-opt" option in the mlton-script file.  But, I can't
explain why "-fno-common" was interpreted as a MLton option, not as
part of the "-cc-opt" option.  I can't reproduce this on my Leopard
install, but I can't imagine that this is a Leopard / Snow Leopard
issue.  Your "svn status" shows no modifications to the
<src>/bin/mlton-script file.

Great.

As John mentioned, you can edit the Makefile (or even override
DESTDIR/PREFIX at the make invocation).
