Bison's "make check" was taking too long for me, so I installed the
following patch to speed up the slowest test by a factor of 10.
"make check" still takes too long, but it's progress.

* tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
abort ();'. This reduces the runtime of the "Many lookaheads"
test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
GCC 3.2.
