The comment regarding SEH and SEH-related macros has been added two lines above. It may not be obvious, but these macros are needed to emit SEH data in mingw/winnt.cc. This group is separated by an empty line; however, it still relates to SEH-related macros. Regards, Evgeny

So, for avoidance of doubt, please drop the vertical space before SSE_REGNO_P to be gentle to the casual/inattentive reader? Or add /* SEH-related */ after the vertical space, to make it clear? thanks
