Bison patch to port to OpenBSD 3.4 (porting problems with echo, isprint)

[Paul Eggert]

I installed this patch to port Bison CVS to OpenBSD 3.4.

2005-07-24  Paul Eggert  <address@hidden>

        * tests/regression.at (Token definitions): Don't rely on
        AT_PARSER_CHECK for data that contains backslashes.  It currently
        uses 'echo', and 'echo' isn't portable if its argument contains
        backslashes.  Problem found on OpenBSD 3.4.  Also, do not assume
        that the byte '\0xff' is not printable in the C locale; it is,
        under OpenBSD 3.4 (!).  Luckily, '\0x80' through '\0x9e' are
        not printable, so use '\0x81' to test.
