NetBSD/macppc kernel status

Recent options/configs used:
makoptions CC="cc -fno-strict-aliasing"
The existing NetBSD source tree may not be complient with 'strict aliasing' defined in ANSI-C starndard. It's been just fortunate this strict-aliasing option was not enabled even with -O2 until gcc-2.95.3 is used as toolchain. Starting gcc-3.x this option is enabled with -O2 and this becomes harmful for NetBSD source tree using union construct. To avoid this issue, set -fno-strict-aliasing till we put all strict-aliasing complient src.
