[MLton-commit] r4604

[Wesley T. <we...@ml...>]

For whatever reason, casting to char makes the test fail on powerpc linux. This is despite that powerpc linux is in fact signed. I've tested the CHAR_MIN variant with -funsigned-char to make sure it fails, and we already include limits.h, so this seems best.
