`--without-tls'
By default the C library is build with support for thread-local
storage if the used tools support it. By using `--without-tls'
this can be prevented though there generally is no reason since it
creates compatibility problems.

Those indicate that something is really wrong.
The compilation process takes several hours even on fast hardware.
Expect at least two hours for the default configuration on i586 for
Linux. For Hurd times are much longer. Except for EGCS 1.1 and GCC
2.95 (and later versions of GCC), all supported versions of GCC have a
problem which causes them to take several minutes to compile certain
files in the iconvdata directory. Do not panic if the compiler appears
to hang.

If you want to run a parallel make, you can't just give `make' the
`-j' option, because it won't be passed down to the sub-makes.
Instead, edit the generated `Makefile' and uncomment the line
# PARALLELMFLAGS = -j 4
You can change the `4' to some other number as appropriate for your
system. Instead of changing the `Makefile', you could give this option
directly to `make' and call it as, for example, `make
PARALLELMFLAGS=-j4'. If you're building in the source directory, you
must use the latter approach since in this case no new `Makefile' is
generated for you to change.
If you want to run a parallel make, simply pass the `-j' option with
an appropriate numeric parameter to `make'. You need a recent GNU
`make' version, though.
To build and run test programs which exercise some of the library
facilities, type `make check'. If it does not complete successfully,

=================================
If you are installing GNU libc on a Linux system, you need to have
the header files from a 2.2 kernel around for reference. You do not
need to use the 2.2 kernel, just have its headers where glibc can access
at them. The easiest way to do this is to unpack it in a directory
such as `/usr/src/linux-2.2.1'. In that directory, run `make config'
and accept all the defaults. Then run `make include/linux/version.h'.
the header files from a 2.2 or newer kernel around for reference. For
some architectures, like ia64, sh and hppa, you need at least headers
from kernel 2.3.99 (sh and hppa) or 2.4.0 (ia64). You do not need to
use that kernel, just have its headers where glibc can access at them.
The easiest way to do this is to unpack it in a directory such as
`/usr/src/linux-2.2.1'. In that directory, run `make config' and
accept all the defaults. Then run `make include/linux/version.h'.
Finally, configure glibc with the option
`--with-headers=/usr/src/linux-2.2.1/include'. Use the most recent
kernel you can get your hands on.
