It's very unlikely to be fixed. The fix mentioned seems to be right, but
without a big-endian Alpha system to test the patch on I wouldn't want to
commit it (big-endian Alpha is a pretty weird configuration, I think the only
one is the Cray T3E supercomputer).

That seems like the right thing to do. Can you please send a patch to
gcc-patches, preferably with test suite results?
