another POSIX shell construct, and less easily avoided because this
comes from upstream.
As of commit 2ca7d52dfa1726aadd1363e399d9b41429332017, which will be in
release candidate 3, configure now contains experimental logic to
address this issue by patching the interpreter line in config.guess and
config.sub when SHELL is not /bin/sh.
I'd already noticed another instance of the problem after I'd sent the
original PR: while e.g. autoconf-generated configure and related in
gcc are very careful to invoke config.guess only prefixed with $SHELL,
runtest.exp exec's it directly, again falling into the trap of POSIX
shell constructs (also $(), maybe more).
The "exec" used in this case is Tcl's exec(n), which simply invokes the
installed copy of config.guess (via the system) with the interpreter
indicated in the file. The patch now applied by configure should
correct this issue.
However, there are more errors still:

There are obviously more hardcoded uses of /bin/sh here and elsewhere,
but I haven't looked for those yet.
If this issue remains in rc3, I repeat my request for execution traces
under both /bin/sh and /bin/ksh for the rc3 version of the dejagnu
launcher script. Please attach the output of "/bin/ksh -x ./dejagnu
report-card" and "/bin/sh -x ./dejagnu report-card" with both run in the
DejaGnu source directory when you get the chance if there are still issues.
I have delayed extending the "shell swap" logic in configure to the
dejagnu launcher script because I am currently uncertain whether it will
help solve any problems.
