- Subject: gcc 3.1 has uint128_t for ppc
With GCC 3.1 CVS I get when compiling glibc:
In file included from ../linuxthreads_db/proc_service.h:20,
from ../linuxthreads_db/thread_dbP.h:6,
from internals.h:36,
from attr.c:23:
../sysdeps/unix/sysv/linux/powerpc/sys/procfs.h:51: conflicting types for `__uint128_t'
<built-in>:0: previous declaration of `__uint128_t'
Ok to commit for both branches?
