Some further info. This came up once before:-

http://sources.redhat.com/ml/libc-alpha/2001-05/msg00239.html

Nobody bothered to answer then. If the fix is not required for glibc, then
it would be good if someone could confirm it, so that the fixincludes
maintainer can add "_G_va_list" to the bypass list.
