Re: strcpy -> strlcpy?
:If you're interested, we've got some simple modifications in the OpenBSD
:gcc (both 2.95 and 3.3) which checks for these kinds of errors. It
:does need relevant functions like strlcpy(3) to be marked up with
:attributes to indicate which arguments are buffers and which are buffer
:sizes.

:I haven't had a chance to feed these back into gcc, but they should be
:pretty easy to extract from the OpenBSD tree, and are documented here:

Well... I think that might be overkill. I can see where it would help
people doing large code updates but in all the code I've ever looked at
in FreeBSD and DragonFly I found that sort of sizeof(pointer) conversion
error only once or twice, a few years ago in the FreeBSD tree. That just
isn't enough to justify maintaining a compiler hack for it.
