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.
it to "."
- include sockio.h if needed to define SIOCGIFCONF (for svr4)
- use POSIX signals and wait macros
- add -S silent flag, so that the client does not print messages unless there
is something wrong
- use flock or lockf as appropriate
- use fstatfs or fstatvfs to find out if a filesystem is mounted over nfs,
don't depend on the major() = 255 hack; it only works on legacy systems.
- use gzip -cf to make sure that gzip compresses the file even when the file
would expand.
- punt on defining vsnprintf if _IOSTRG is not defined; use sprintf...
To compile sup on systems other than NetBSD, you'll need a copy of daemon.c,
vis.c, vis.h and sys/cdefs.h. Maybe we should keep those in the distribution?
