The installed MLton is 20100504, so the problem you mentioned hasn't been
observed. In fact, I tried to build MLton (by MLton) from the source
root, and after I copied the generated "mlton-compile" to /usr/lib/mlton, 
it works fine. :-)

Maybe we've not decribe our difficulty clear. We followd these
steps to try to build an smlnj heap image (just as you mentioned in a 
previous post):
1. run "make" at the source root;
2. run "make smlnj-mlton"
3. copy the generated "mlton-smlnj.x86-linux" to "build/lib/"
4. remove "mlton-compile" in the "build/lib/"
5. run the script "mlton" in the "build/bin"
but we got the error message:
"unknown switch: -fno-common:
just as in the previous post.

Is there something we forgot?
