  Gnulib module: strstr or strstr-simple
  
  Portability problems fixed by either Gnulib module @code{strstr-simple}
  or @code{strstr}:
  @itemize
  @item
  This function can trigger memchr bugs on some platforms:
  glibc 2.10.
  @item
  This function can trigger false positives for long periodic needles on
  some platforms:
  glibc 2.12, Cygwin 1.7.7.
  @item
  This function may fail to find matches on some platforms:
  glibc 2.28.
  @end itemize
  
  Portability problems fixed by Gnulib @code{strstr}:
  @itemize
  @item
  This function has quadratic instead of linear worst-case complexity on some
  platforms:
  glibc 2.8, macOS 11.1, FreeBSD 6.2, NetBSD 9.0, OpenBSD 4.0, AIX 5.1, HP-UX 11, IRIX 6.5, Solaris 11.4, Cygwin 1.5.x, mingw, MSVC 14.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  This function cannot work correctly on character strings in most multibyte
  locales.  Gnulib provides an alternative function @code{mbsstr} that works
  on character strings in all locales.
