pthread issue on OpenSUSE 10

Hello!

I am working on an application that uses gcc-2.95 libs.
When linking I got the following error:
------------
../gcc-2.95/lib/libstdc++.a(isgetline.o): In function `istream::getline(char *, int, char)':
../gcc-2.95/linux/i686-pc-linux-gnu/libio/../../../gcc-2.95.3/libio/isgetline.cc:41: undefined reference to `_pthread_cleanup_push_defer(_pthread_cleanup_buffer *, void (*)(void *), void *)'
../gcc-2.95/linux/i686-pc-linux-gnu/libio/../../../gcc-2.95.3/libio/isgetline.cc:41: undefined reference to `_pthread_cleanup_push_defer(_pthread_cleanup_buffer *, void (*)(void *), void *)'
../gcc-2.95/linux/i686-pc-linux-gnu/libio/../../../gcc-2.95.3/libio/isgetline.cc:54: undefined reference to `_pthread_cleanup_pop_restore(_pthread_cleanup_buffer *, int)'

I am linking with the following flags:
-L/usr/local/lib -liberty -lstdc++ -Wl,--export-dynamic  /usr/lib/libpcre.a  -lXm -lXp -lXext -lXt -lX11  -ldl -lm -lpthread
and with gcc4.1.0.

I am stuck up with this problem because I have not seen such on any redhat : from fc3 to fc6.
The same situation is on SuSe Linux Enterprise Server 10.

Thanks!
