Under FT_LONG64 FT_DivFix truncates the result at 32 bits, see ftcalc.c:271. Interestingly, FT_MulFix and FT_MulDiv do not do that, although it also is possible for them to exceed 32 bits in the result. Which behavior would be correct? IMHO a function specified as FT_Long should not truncate at 32.
