I think your source tree is out of date; I recently committed changes to 
the runtime/basis/System/Time.c, along with corresponding changes to 
/basis-library/system/time.sml:
   http://mlton.org/pipermail/mlton-commit/2007-December/002275.html
You need to 'make runtime ; make basis' to push the changes from both the 
runtime and the basis to the 'build' directory.

BTW, I recommend moving any furthe discussion of a Win64/MinGW port to the 
mlton at mlton.org (development) mailing list.
