True, but I proposed assuming C89 in October and asked for objections
<http://mail.gnu.org/archive/html/bison-patches/2002-10/msg00011.html>.
Nobody objected.

That bitset implementation is not in GCC 3.2.2, and the last reference
I saw to it in the GCC mailing lists was in May:
<http://gcc.gnu.org/ml/gcc/2002-05/msg02532.html>.  I'll CC: this
message to Michael Hayes to see if he can shed more light on its
status in GCC.
