Make sure that each va_start has one and only one matching va_end,
especially in error cases.
If the va_list is used multiple times, do multiple va_starts/va_ends.
If a function gets va_list as argument, don't let it use va_end (since
it's the callers responsibility).
Improved by comments from enami and christos -- thanks!
Heimdal/krb4/KAME changes already fed back, rest to follow.
Inspired by, but not not based on, OpenBSD.
- files removed in binutils 2.8.1 or 2.9.1
- some testsuite stuff
- VMS, MS-DOS, and MPW Macintosh build environmanet (most of which are
quite old and out of maintenance)
- generated GNU info files
- non-NetBSD-target makefile fragments
