945bd69ebd The old mips modf didn't work (pr 1048). This replaces it with 
a version that does work on little-endian MIPS CPUs. Not tested on
big-endian MIPS; the "li.d" may be byteorder-dependent.

946af1bccf Fix an old bug, whereby ASMSTR() was used before #including "SYS.h", where 
it was defined.
