This function returns incorrect values in some cases, such as when
given an empty needle:
-glibc <= 2.0, Cygwin 1.5.x.
+glibc <= 2.0, Solaris 11 2011-11, Cygwin 1.5.x.

Performance problems fixed by Gnulib module @code{memmem}:
@item
This function has quadratic instead of linear worst-case complexity on some
platforms:
-glibc 2.8, FreeBSD 6.2, NetBSD 5.0, AIX 5.1, Solaris 11 2010-11, Cygwin 1.5.x.
+glibc 2.8, FreeBSD 6.2, NetBSD 5.0, AIX 5.1, Solaris 11 2011-11, Cygwin 1.5.x.
Note for small needles the replacement may be slower.
