Heh. That was with bash as shell. But without fiddling with the SHELL
variable, I get this failure:

FAIL: high-bit-range

The reason is that this shell's printf built-in does not interpret the
\x81 escape sequence. It does interpret \201 as an octal escape sequence,
though.

$ bash -c "printf '\\x81'" | od -t x1
0000000  81
0000001
$ /bin/sh -c "printf '\\x81'" | od -t x1
0000000  5c 78 38
0000003
$ /bin/sh -c "printf '\\201'" | od -t x1
0000000  81
0000001

While at it, let me also fix a bashism (while avoiding backslashes inside
backquote). I've tested this fix:


2011-11-11  Bruno Haible  <address@hidden>

        Fix high-bit-range test failure on OSF/1 5.1.
        * tests/high-bit-range: Use octal escape instead of hexadecimal escape
        sequence. Avoid $(...) syntax.
