{ZW} Even if you are using a 2.0 kernel on your machine, we recommend you
compile GNU libc with 2.1 kernel headers. That way you won't have to
recompile libc if you ever upgrade to kernel 2.1 or 2.2. To tell libc which
headers to use, give configure the --with-headers switch
(e.g. --with-headers=/usr/src/linux-2.1.107/include).
Note that you must configure the 2.1 kernel if you do this; otherwise libc
will be unable to find <linux/version.h>. Just copy .config from your 2.0
kernel sources to the 2.1 tree, do `make oldconfig', and say no to all the
new options.

1.15. I get failures during `make check'. What shall I do?
{AJ} The testsuite should compile and run cleanly on your system, every
failure should be looked into. Depending on the failure I wouldn't advise
installing the library at all.
You should consider using the `glibcbug' script to report the failure,
providing as much detail as possible. If you run a test directly, please
remember to set up the environment correctly. You want to test the compiled
library - and not your installed one. The best way is to copy the exact
command line which failed and run the test from the subdirectory for this
test in the sources.
There are some failures which are not directly related to the GNU libc:
- Some compiler produce buggy code. The current egcs snapshots are ok and
the not yet released egcs 1.1 should be ok. gcc 2.8.1 might cause some
failures, gcc 2.7.2.x is so buggy, that explicit checks have been used so
that you can't build with it.
- The kernel might have bugs. For example on Linux/Alpha 2.0.34 the
floating point handling has quite a number of bugs and therefore most of
the test cases in the math subdirectory will fail. The current Linux 2.1
development kernels have fixes for the floating point support on Alpha.
