Richard S, I suspect your bit field changes.  I'll have a look at it
myself tomorrow if you don't find it first.

Most likely the same issue as reported on sparc, PR 55391.

Yeah, I expect it is, sorry.  'Fraid I couldn't get the testcase to fail
in a cross compiler though.  At first I was getting a load of warnings
about visiblity not being supported, etc., so I built cross binutils
and pointed configure at them.  That silenced all the warnings but the
cc1plus command still succeeded.  I suspect something important is
still configured out, but I couldn't tell what from a scan of auto-host.h.

I now suspect you're missing --with-long-double-128, which would have been
auto-detected given alpha glibc headers in --with-sysroot, as I have.

Proposed patch here:
