gcc-2.95 build FAILED! - RedHat Linux/Alpha 5.2

[abel@bfr.co.il (Alexander L. Belikoff)]

Yep - justs failed to build on:

- Alpha dp264 (dual CPU)
- RedHat 5.2
- egcs 1.1.2, binutils 2.9.1.0.15-1

This is pretty painful and surprising, considering that egcs-19990712
built just fine. Anybody cares to fix that or just "stick to RedHat
6.0, you pathetic looser!" ;-)

We are slowly migrating on our Alphas from RedHat 4.2 to RedHat 5.2.
6.0 is out of question - there are too many complaints about general
stability and speed. On RedHat 5.2 the situation with the compilers is
the following:

1. Egcs 1.0.3 (supplied by RedHat) - gives ICE on certain optimization
   flags (I reported it quite a while ago).

2. Egcs 1.1.2 (built manually) - has the infamous memcpy bug.

3. Gcc 2.95 - fails to build.

This doesn't look very optimistic, does it? ;-) Anyway, here goes the
make log:

PS. In case you are going to suggest upgrading binutils, could you
please also explain what exactly was fine with the latter package 3
weeks ago, that got horribly wrong now?..

Thanks in advance,
