Thanks for reporting that, though as Hans Aberg notes it's better to
report bugs to address@hidden I installed the following patch.
By the way, I suggest you use Bison 2.3 rather than 2.1, as it should
be a bit more reliable.

* data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
rather than a for-loop that declares a local bool variable. This
should work around a compatibility problem with a Cray x1e C++
compiler reported by Hung Nguyen in
<http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
The for-loop was introduced in the 2004-11-17 change but I don't
know why it was needed.
