2.6.0-t1-ac2: unable to compile glibc 2.3.2

Hi there!

I just tried to update my glibc to 2.3.2 and saw that glibc can't compile
because of linux/sysctl.h.

I added the line "#include <linux/compiler.h>" to sysctl.h.
(since sysctl needs the __user)

So someone forgot the line, or did I miss something?

Regards,
Martin

you're probably better off using not-the-kernel headers for building
glibc. eg on a RHL distro it's glibc-kernheaders package, other distros
have different package names for these files.

No, you should not use the kernel headers directly - use a sanitized
version (can get one from redhat's kernel-headers package).  Else
just add a '#define __user' before that struct.

In the past I would grab the headers of the kernel of which I compiled
glibc against.  glibc has #ifdefs in it to turn on/off some features
based on the kernel version.

Are there plans get a sane set of kernel headers together that can be
used by userspace (at least glibc) that properly describe the features
of the current kernel, so the C library may take advantage of them?
