I have tried to compile with defined __rs6000__ and make reports following error
g++ -shared -nostdlib
/usr/lib/gcc-lib/powerpc-suse-linux/3.3.3/crtbeginS.o .libs/cl_abort.o
 ...  -Wl,--rpath -Wl,/usr/lib/../lib -Wl,--rpath -Wl,/usr/lib/../lib -L/usr/lib/gcc-lib/powerpc-suse-linux/3.3.3 -L/usr/lib/gcc-lib/powerpc-suse-linux/3.3.3/../../../../powerpc-suse-linux/lib/../lib -L/usr/lib/gcc-lib/powerpc-suse-linux/3.3.3/../../../../powerpc-suse-linux/lib -L/usr/lib/gcc-lib/powerpc-suse-linux/3.3.3/../../../../lib -L/usr/lib/gcc-lib/powerpc-suse-linux/3.3.3/../../.. -L/lib/../lib -L/usr/lib/../lib /usr/lib/../lib/libstdc++.so -lm -lc -lgcc_s /usr/lib/gcc-lib/powerpc-suse-linux/3.3.3/crtsavres.o /usr/lib/gcc-lib/powerpc-suse-linux/3.3.3/crtendS.o /usr/lib/gcc-lib/powerpc-suse-linux/3.3.3/../../../../lib/crtn.o  -Wl,-soname -Wl,libcln.so.4 -o .libs/libcln.so.4.0.1

collect2: ld returned 1 exit status
make[1]: *** [libcln.la] Error 1
make: *** [all] Error 2

though everything was compiled with -fPIC:
g++ -O -I../include -I../include -I./base -c ./base/output/cl_prin_globals.cc  -fPIC -DPIC -o .libs/cl_prin_globals.o

Maybe this is completely different problem and it is concerned with
system i'm compiling on so i post again my configuration:

Linux blade1 2.6.5-7.252-pseries64 #1 SMP Tue Feb 14 11:11:04 UTC 2006 ppc64 ppc64 ppc64 GNU/Linux

> OK, you are compiling in PowerPC 32-bit mode, but CLN's configuration was

> The immediate workaround for you is to change include/cln/config.h so that it
