Update to R33d:

No changes in mksh R33c except for Ultrix support. None in R33d.

In mksh R33b, much more compilers are detected, even if not all of
them are supported. The OE (OS and CC/LD) versions are now dumped
too. Instead of #error, forced link failures are now used as the
mechanism to auto-detect some things in the target environment.
Features are now much better detected, and some annoying warnings
don't show up any longer due to this.  Less tools are required to
build.

Please be reminded that you should run ./test.sh -v inside an
environment with /dev/tty available (as device node) and usable
(e.g. use script(1) or GNU screen if you're doing auto-builds
detached from controlling terminal). Use -v to see failures.

No surprises in mksh R33 either, but the build system now gives
more detailed output on the version actually built, to aid tracking
down FTBFSen (build errors) with access to only the build logs.
Regression tests now work with Intel's compiler on SLES too, which
requires a custom LD_LIBRARY_PATH formerly stripped by the script.
