Thanks Paul,

I found another potential problem in testsuite script syntax:

address@hidden [temp/autoconf]> /bin/sh -n ./tests/testsuite
./tests/testsuite: syntax error at line 1241: `^' unexpected

        *[^\\]"$at_lf"*) at_reason='an embedded newline' ;;

As specified in autoconf info, many shells does not support `^' to
negate character classes (such as Tru64 /bin/sh).
