Newer versions of gcc give this warning message. It's actually been in
the tempnam(3) manpage on Linux for some time:
BUGS
The precise meaning of `appropriate' is undefined; it is
unspecified how accessibility of a directory is deter-
mined. Never use this function. Use mkstemp(3) instead.
Unfortunately, mkstemp(3) has different semantics, so it isn't a drop-in
replacement. Furthermore, not all systems have mkstemp(3), and tempnam(3)
is still better than mktemp(3).
