 Can you try to build your system with that "struct sigframe"
 definition just commented out?
 This is never used afaics -- I've already removed it in my
 source tree but I'm still running some test compilations to
 make sure nothing still refers to it.

 best regards
 Matthias

 Yep: Kernel compiles fine now!

 I've removed the "struct sigframe" now (after my pmax
 build completed successfully).
 Besides that, I've rearranged some more compat stuff to
 allow building COMPAT_ULTRIX without any NetBSD COMPAT
 option.
 Can you try whether your configurations still build?
 best regards
 Matthias

 Yep again: I've just rebuilt kernel (and complete userland) and
 everything is running fine (w/o COMPAT_16).
