Hi,
Building krb5 1.11.3 fails on NetBSD 5.1 with the following error:

Would it be possible to fix the issue for the next krb5 release?
(Maybe by not using the gcc "-Werror=variadic-macros" flag?)
Commit d211001ba17fddfb952beb00118dc5c7e598355e on git master has resolved
the issue (I saw it on FreeBSD as well, though only as a warning). It
does not appear to be marked for pullup to the 1.11 branch, though; I'll
look at whether that's reasonable to do.
