Is this change of a comment deliberate?  I thought you were avoiding 
changing comments.

Is it deliberate that this (in e_logl.c) is not becoming integer 0 (it may 
well make sense to avoid converting to integers in such generated tables, 
but you didn't call it out in the patch description as a deliberate 
fixup)?  Likewise in s_atanl.c.
