I revisited these two kernel files and agree partially with your assessment:
- machdep.c fixed a missing linebreak; the other change (mc_len) was cruft.
- ucontext.h contains the protos for the *context routines; they still need
to be somewhere so autoconf can find them, and I felt that this was the best
place for them.  The other stuff (uc_flags, UCF_SWAPPED) was cruft.
