gcc-4.1.0, and glibc-2.3.4. Looks like the 2.6.16 kernel changed

any to build against a 2.6.16 kernel, but I'm making everyone aware of
this anyway. :)

Thanks for the link to the thread. So, I guess the patch submitted by
the thread starter was rejected?
Yes, it was. Kernel headers have been gradually breaking for a _very_ long
time, WRT their #include'ing by userland apps. Instead of changing the
kernel build system to monitor the situation, kernel hackers have decided
re-design /usr/src/linux/include/ from scratch. Last I checked, a first
implementation of this rework is scheduled to show up in 2.7 kernels.
Your message refers to using kernel headers when building glibc. Why
would that be the issue for me since I haven't touched glibc since I
first installed it, which was after it first came out? Is the idea
being when I upgraded to glibc-2.3, it used kernel headers *back then*
so each subsequent upgrade continued to do so?
"I haven't touched glibc since I first installed it" is a contradiction of
"when I upgraded to glibc-2.3".
Be that as it may, there are several possibilities here. You might still
have the old /usr/include/{linux,asm} -> /usr/src/linux/include/{linux,asm}
symlinks. Or you might have omitted upgrading the laundered kernel header
package for your distribution and/or kernel when upgrading glibc (even
assuming it was from binaries). Or you rebuilt glibc from source pointing it
directly at unlaundered kernel headers you had installed at the time. Or,
or, ...
In any case, I am loathe to commit an ever-increasing set of workarounds for
a problem kernel maintainers not only admit to, but also have yet to fix.
This whether or not such workarounds are always possible, which isn't the
case.
Marc.
