[MLton] starting builds

So! I've been looking into this some more.
It's definitely a bug in libc on hppa! (the rounding)

In libc (2.3.5-6) the problem appears.
In libc (2.3.2.sd1-22) the problem is not present.

The *same* MLton binary rounds/fails on the different library.
The unhandled excepion: Fail: bug appears on both.

Further testing seems to indicate that *gcc* (!!!)
is compiling the assembler in libc wrong.
