Can you explain how returning "unknown" is different from returning some minimal known alignment? Comments like: > ! /* Compute values M and N such that M divides (address of EXP - N) and > ! such that N < M. Store N in *BITPOSP and return M. suggest that M=1, N=0 is always a valid conservative thing to return. If there is a difference, the comment should explain what it means. Thanks, Jay.
