Hi, i'm trying to compile Glibc-20051024

for the sparc32 arch and the compile fails with the following error:

../nptl/sysdeps/unix/sysv/linux/sparc/lowlevellock.h:95:2: error: #error 
SPARC < v9 does not support compare and swap which is essential for 
futex based locking

Here's my setup:

- clfs book = CLFS-SVN-20051110
- host = Linux 2.6.13-gentoo-r5 #1 Sat Nov 5 08:35:40 EST 2005 i686 AMD 
Duron(tm) Processor AuthenticAMD GNU/Linux (Gentoo 2005.1)
- package = Glibc-20051024 (Section 5.7)
- target = sparc32 (Javastation-1, Mr.Coffee)

I've tried with gcc 3.3.6 and gcc 4, same error.

Same thing on Ubuntu 5.10.

In section 1.3:

Sparc v8 and earlier

   Sparc v8 and earlier processors are not supported by NPTL. Sparc v9
   are supported by the Sparc 64 build instructions which utilize NPTL.
   If you have an UltraSparc processor, you have a Sparc v9 which is 64

How is it possible to disable NPTL ? Or does it mean that it is not 
possible to build lfs on sparc32 arch ?
