If you want to compile uClibc with NPTL support, then answer Y.
- IMPORTANT NOTE! NPTL requires a Linux 2.6 kernel, binutils
- at least version 2.16 and GCC with at least version 4.1.0. NPTL
- will not work with older versions of any above sources. If you
- ignore any of these guidelines, you do so at your own risk. Do
- not ask for help on any of the development mailing lists.

- !!!! WARNING !!!! BIG FAT WARNING !!!! REALLY BIG FAT WARNING !!!!
-
- This is experimental code and at times it may not even build and
- even if it does it might decide to do random damage. This code is
- potentially hazardous to your health and sanity. It will remain
- that way until further notice at which point this notice will
- disappear. Thank you for your support and for not smoking.
