OK, how about the following more-conservative change instead? This
patch uses correct version numbers for future versions of SunOS /
Solaris, while leaving the existing incorrect numbers in place. This
is an upward compatible change that shouldn't affect existing code
that depends on the existin numbers, and this should avoid the
backward-compatibility hassles that have been mentioned in this
thread.

* config.guess, config.sub: Use names like "sunos5.10" for future
Solaris versions, thus fixing the incorrect version numbers
(like "solaris2.9") in the old scheme.
