Thanks; I'll look at this.

: 2) Many files get updated with no change except for the header.

Shouldn't happen as of quite a while ago; there's a heuristic check that
avoids overwriting if ony the file header is changes by grepping out the
header.

What spurious changes?  config.guess is not used for `real' configury
(there's an explicit --host=), so this might be simply an informational
message and not functionally different.

: A side-effect, is that all no-op comment blocks are removed.

This is actually a bad thing; we want the config.h files to be as close to
`real' config.h as possible for comparison purposes.

: config.guess now omits the vendor portion entirely, on all platforms,
: just like ${MACHINE_GNU_PLATFORM} in bsd.own.mk.

This goes against the standard config.guess style, so it shouldn't be
changed.  config.guess should use "unknown" as the vendor field if it is
irrelevant or not known.

(We use --host explicitly, since our ${MACHINE_GNU_PLATFORM} omits the OS
version number, and the omission of the vendor field is simply a convenience
in that case.)

: I'm not sure if it would still be OK on m68k/a.out (probably *not*),

No.  New toolchain builds for m68k are *ELF*.  When all is said and done,
some a.out compatibility may be re-added for old NetBSD releases (compiling
gcc out-of-the-box), but that's really low priority.
