Hi,


I am unable to build for powerpc.


I run configure with theses parameters:
CC="/home/wiktor/powerpc-e500v2-linux-gnuspe/bin/powerpc-e500v2-linux-gnuspe-gcc"
CROSS_COMPILE="powerpc-e500v2-linux-gnuspe-"
CFLAGS="-msoft-float"
LDFLAGS=""
CROSS_COMPILE=$CROSS_COMPILE LDFLAGS=$LDFLAGS CFLAGS=$CFLAGS CC=$CC
ac_cv_build=$CROSS_COMPILE ac_cv_target=$CROSS_COMPILE
ac_cv_func_malloc_0_nonnull=yes ./configure --host=powerpc
--prefix=/home/wiktor/root_dir/ppc
-includedir=/home/wiktor/root_dir/ppc/include &&

This is rather confusing since urcu-call-rcu-impl.h does include the
correct header file were uatomic_or exists(uatomic/generic.h).


Is there a specific macro that has to be included in CFLAGS? like -DPPC
or -D__PPC__ ?
