unfortunately, this doesn't match my experience at all: 5.1 introduced a
new assembler, which causes the bootstrap to break for me and several other
people.  I've posted a couple of patches to get further along on 5.1, but
most of them are still unreviewed:

* Use old assembler to allow bootstrapping:

  http://gcc.gnu.org/ml/gcc-patches/2001-02/msg01448.html

* Initial port of libstdc++ v3 to allow it to compile:

  http://gcc.gnu.org/ml/gcc-bugs/2001-03/msg00281.html

* Define __X_FLOAT for proper long double support:

  http://gcc.gnu.org/ml/gcc-patches/2001-04/msg00213.html

* Detect _Bool in bootstrap compiler to allow bootstrapping with cc (older
  gcc's don't work unless hacked to use the old assembler as well):

  http://gcc.gnu.org/ml/gcc-patches/2001-04/msg00607.html

From the GCC 3.0 Release Criteria (Open Issues), it still seems to be
undecided whether to use Alpha GNU/Linux or Tru64 UNIX as the primary
evaluation platform on alpha, and Tru64 isn't even listed in the secondary
evaluation platform list.  It looks like nobody cares too much for Tru64
UNIX nowadays.

This lack of attention/feedback in these issues is very frustrating ;-(
