Re: Libc patch no longer applies

[Thomas Schwinge]

Hi!

IRC, freenode, #hurd, 2011-09-15:

    <tschwinge> Hooray!  I found my glibc source and build (!) directories from
      2010-04.
    <tschwinge> String dump of section '.comment':
    <tschwinge>   [     1]  GCC: (Debian 4.4.3-3) 4.4.3
    <tschwinge> Aha.  Good.
    <tschwinge> And binutils 2.20.1.20100303.
    <tschwinge> I'm inclined to say that it is a tools issue.  The source tree
      doesn't have any modifications.
    <tschwinge> I can do a crosscheck.
    <tschwinge> Over night.  Perfect.

... and this did work!  That is, ``--build=i486-gnu --host=i486-gnu''
configuration with GCC 4.4, plus old binutils downgraded to Debian
package 2.20.1-2.

And, on the other machine (with the 2010-04 trees), I built with recent
binutils as a crosscheck.  As expected, I got the same failure as we've
seen before.  The specific GCC 4.4 version doesn't appear to matter.

I will next compare the object files of the two builds that only differ
w.r.t. binutils.

And on we go!  Testsuite.  As we know, there is quite a baseline of
failures.

Additional failures compared to Debian.

All the many SO-found-found ones are due to configuring with
--prefix=/usr instead of --prefix= -- but Debian also has --prefix=/usr,
so I guess they have a patch for that.  Will go looking.

A bunch of the other failures are probably new; others are not nice but
not too worrying either.  Hopefully some will go away as soon as I update
From the 2010-04 glibc sources.
