  Gnulib module: memmem or memmem-simple
  
  Both modules implement the same replacement for the @code{memmem} function
  with the memmem module providing a replacement on more platforms where
  the existing @code{memmem} function has a quadratic worst-case complexity.
  
  Portability problems fixed by either Gnulib module @code{memmem-simple}
  or @code{memmem}:
  @itemize
  @item
  This function is missing on some platforms:
  Mac OS X 10.5, FreeBSD 5.2.1, OpenBSD 4.0, Minix 3.1.8, AIX 4.3.2, HP-UX 11, IRIX 6.5, OSF/1 5.1, Solaris 10, mingw, MSVC 14, Interix 3.5, BeOS.
  @item
  This function has reversed arguments on some older platforms:
  Linux libc 5.0.9
  @item
  This function can trigger false positives for long periodic needles on
  some platforms:
  glibc 2.12, Cygwin 1.7.7.
  
  @item
  This function returns incorrect values in some cases, such as when
  given an empty needle:
  glibc <= 2.0, Solaris 11.3, Cygwin 1.5.x.
  @end itemize
  
  Performance problems fixed by Gnulib module @code{memmem}:
  @itemize
  @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 11.3, Cygwin 1.5.x.
  Note for small needles the replacement may be slower.
