+ [BZ #22685]
+ * sysdeps/powerpc/powerpc32/sysdep.h (ABORT_TRANSACTION_IMPL): Renamed
+ from ABORT_TRANSACTION.
+ (ABORT_TRANSACTION): Redirect to ABORT_TRANSACTION_IMPL.
+ * sysdeps/powerpc/powerpc64/sysdep.h (ABORT_TRANSACTION,
+ ABORT_TRANSACTION_IMPL): Likewise.
+ * sysdeps/unix/sysv/linux/powerpc/not-errno.h: New file. Reuse
+ Linux code, but remove the code that aborts transactions.
