Apologies if this has already been reported/fixed - I've had a quick
search and not found anything.

cvsup'd about 2 hours ago after same failure from yesterday, still no
joy:

/usr/tool/bin/i386--netbsdelf-gcc -O2  -Wall -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Wno-uninitialized -Werror   -nostdinc -idirafter /usr/include -c mountd.c
mountd.c: In function `main':
mountd.c:352: `IPV6_BINDV6ONLY' undeclared (first use in this function)
mountd.c:352: (Each undeclared identifier is reported only once
mountd.c:352: for each function it appears in.)
*** Error code 1

Stop.
make: stopped in /usr/src/usr.sbin/mountd
*** Error code 1
