>Description:

Attempting to build a kernel with Vinum support enabled (pseudo-device
vinum) will cause the kernel build to fail due to a warning generated
by /usr/src/sys/dev/vinum/vinumdaemon.c:

*** BUILD ABORTED ***
-----

This problem has existed for several weeks now.  I don't know if it
exists on other architectures, as I've only tried compiling Vinum
support on NetBSD/alpha.

Note that other Vinum files also suffer from warnings breaking the build:

-----

*** Failed target:  vinumrevive.o
-----

This problem affects any (alpha?) kernel config that includes
"pseudo-device vinum", not just GENERIC.

>How-To-Repeat:

With recent sources, do the following:

cd /usr/src
cp /usr/src/sys/arch/alpha/conf/GENERIC /usr/src/sys/arch/alpha/conf/GENERIC-VINUM
echo 'pseudo-device vinum' >> /usr/src/sys/arch/alpha/conf/GENERIC-VINUM
./build.sh tools kernel=GENERIC-VINUM

>Fix:

Compiling vinumdaemon.c, vinuminterrupt.c, and vinumrevive.c without
"-Werror" allows the kernel build to complete.  (Eliminating those
warnings is a better way to ensure that happens, though.:)
