Jiri, I suspect several people looked around and then assumed another
person was handling this change :-( Sorry.
One cosmetic tweek for the ChangeLog. x86-64linux.mh et.al. should read
config/i386/x86-64linux.mh et.al. - the full path to files in sub
directories is needed.
Everything is fine except the tweek to xm-i386.h. The xm file is for
host configury, not native configury. I suspect you ment to add it to
config/i386/nm-<something>.h.
