I think what is meant is: Will compile correctly on...
without patches that is...and I'm reading minds here, so if I'm
completely wrong, well...oh well :)

yeah, but I see where he's coming from... although, I want to impliment
glibc-2.2 as soon as possible...there are some problems with 2.1.3
(security and whatnot) that are addressed in 2.2...I still have to build
a system with 2.2, which I hope to do this weekend... but it will most
likely be the next weekend, knowing my schedule...
but, 2.2 is a major release...sort of a .0 in some ways (should be
glibc-2.2.0 :> ...)
I think one thing that people miss is that the reason that we were all
having trouble compile LFS on glibc-2.1.9x and 2.2 systems was because
many of the packages haven't been rebuilt with it's little gotcha's in
mind... Most of these packages had programs that weren't built with the
strictest standardization in mind... Those are the problems I've read
about in the glibc-2.2 ... In other words, it is my feeling that we
should at least wait for some of those packages to be updated...if that
means we wait for gcc-2.95.3 ..then, so be it...it shouldn't be that
long... they've released a test version already... Then again, I said
the same thing when linux-2.4.0-test1 came out :)
(btw, I have tried building LFS from an RH7.0 box with updated glibc-2.2
rpm's... I found that the same problems exist there. If anyone else has
had different experiences, I'm all ears...there could be problems with
rh's implimentation of 2.2 ... Red Hat make a mistake??? No - Never!!

I haven't noticed any issues that I can track to glibc-2.2 and
gcc-2.95.2 (or EGCS 2.91.66)... But I can say that kernel 2.2.17 DOES
NOT compile with glibc-2.2 and gcc-2.96 ... Of course, that's rh7's
compiler... But I think that the difference here is that the gcc-2.95.x
line is code-related to later EGCS releases... In otherwords, they
shouldn't be all that different... generally speaking...
whereas the gcc-3.0 line supposedly doesn't carry the same type of
support as 2.95.2 did... so, again, major release syndrome...however,
kernel 2.2.18 DOES compile with gcc-2.96 with my tests... Appearently,
the problem was fixed...

personally, I think that the mark should be when a major release
(glibc-2.2) causes more patches to be added to code simply to make the
code compile, then we shouldn't upgrade to that version... at least,
regarding major software...
Has anyone had success building a clean gcc-2.95.2 source tree without
How about Fileutils?
I mean, the fileutils problem was fairly major...on my system, ls didn't
print to standard output... Now, perhaps that was the only problem and
perhaps the patch fixed it, but I'll feel a little bit better once that
patch is implimented into a release...
I mean, don't get me wrong, I don't mind patching and fixing things at
all, but these base level programs are a little bit too important to
have obscure gotcha's hanging around in....
Perhaps the answer is to give an option for installing glibc-2.2 in the
book... Perhaps that's a horrible idea from a support standpoint... but
maybe it's the only way to please everyone...
