...
The implementation is from NetBSD, with the addition of mempcpy (a GNU
extension) for parity with glibc and libssp.

While, like on some of those systems, it is automatically included by
<locale.h> with the proper feature test macros, its presence under this
particular name is still presumed in real-world software.

Feature test macros overhaul: string.h and strings.h overlaps

strings.h is the header mandated for these functions in POSIX.1 prior to
2008 (when most of these were removed). The declarations in string.h are
only for BSD compatibility. But when both headers are included, avoid
duplicate declarations.
Also, mark stpcpy and stpncpy as POSIX.1-2008.

Rework handling of basename variants
...
As a commonly-included header, the #define basename in <string.h> can
affect code which uses "basename" for its own purposes (e.g. struct
members or C++ namespaced functions). When such cases occur and some
code includes <string.h> and some not, then errors result. OTOH,
<libgen.h> is rarely used, and that's where the renaming occurs in
glibc, so code using <libgen.h> should already be safe.
* libc/include/libgen.h (basename): Define as __xpg_basename
for source compatibility with glibc.
Declare with __ASMNAME("basename") for ABI compatibility.
* libc/include/string.h (basename): Define as basename for
source compatibility with glibc.
