Hello

Building a kernel (from -current sources) containing 'options
COMPAT_LINUX' fails on my NetBSD/alpha 3.99.3. Cross-building
(i386->alpha) the same kernel config on my i386 succeeds. Anyone else
seeing this?

*** BUILD ABORTED ***


Commenting out options COMPAT_LINUX gets the build through on the Alpha.
Apart from the kernel native build also the native distribution target
fails. Also here cross-building a distribution will succeed. Don't have
a build log from that available though.
