--- Comment #6 from H. Peter Anvin <hpa at zytor dot com> --- No idea what you mean with #asmoptions. Using hacks in the Makefile is equivalent to having to do dependencies by hand (keep in mind that these statements will generally be part of header files.) In other words, it would mean the -M* options are useless as we would now need to create a completely separate mechanism to generate this information – at which point we might as well use it for C as well.
