Diff to previous 1.4 (colored)
Change basename(3) and dirname(3) to return a pointer to static storage, rather than modifying their input arguments. While not reentrant, this is explcitly allowed by IEEE Std 1003.1-2001 (which allows either behavior, stating that it is implementation-dependent). The new semantics are considered less hostile/more useful by most programs which use basename(3) and/or dirname(3) (several programs in the NetBSD tree reimplement basename()/dirname() themselves to avoid modification of the input argument). This new implementation truncates results to PATH_MAX. The Std does not address this in the static storage case. However since PATH_MAX is the maximum pathname length in the Std, this should not be a problem in practice. Nontheless, it is noted in the BUGS section. See the basename(3)/dirname(3) regression tests in src/regress/lib/libc. Inspired by discussion with Niels Provos, related to PR 18647.
