glibc diff -> nptl solution -> wtf?

[Stefan Wold]

This is my output for nptl, however I'm still on gcc-3.4.4, havn't tested 
to build glibc with gcc 3.4.5, but I can try that of course.

gcc -v:
Reading specs from /usr/lib/gcc/i686-pc-linux-gnu/3.4.4/specs
Configured with: ../configure --host=i686-pc-linux-gnu 
--enable-languages=c++ --prefix=/usr --infodir=/usr/share/info 
--mandir=/usr/share/man --enable-__cxa_atexit --enable-threads 
--disable-nls --enable-target-optspace --with-gnu-ld --with-system-zlib 
--enable-shared

gcc version 3.4.4

My configure flags in glibc BUILD look like this:
  ../configure --host=$BUILD                          \
                --build=$BUILD                         \
                --enable-add-ons                       \
                --enable-kernel=2.6.0                  \
                --with-elf                             \
                --with-headers=/usr/src/linux/include  \
                --with-gd=no                           \
                --without-cvs                          \
                --enable-shared                        \
                --infodir=/usr/share/info              \
                --mandir=/usr/share/man                \
                --prefix=/usr                          \
                $OPTS                                  &&

Sincerely
