errc, warnc

[Robert Millan]

Hi!

How would you feel about adding errc(), warnc(), verrc() and vwarnc() ?

They're the same as err(), warn(), verr() and vwarn() with the exception that an
additional argument is overrides errno.

These functions were introduced in FreeBSD 3.0 and are not in BSD 4.4 or any
standard, although I think they would be good to have for compatibility.

Want me to send a patch?
