POSIX specification: http://www.opengroup.org/susv3xsh/strstr.html

Gnulib module: strstr

Portability problems fixed by Gnulib:

  * This function has quadratic instead of linear worst-case complexity on some platforms: glibc 2.8, MacOS X 10.3, FreeBSD 6.2, NetBSD 3.0, OpenBSD 4.0, AIX 5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, Solaris 10, Cygwin 1.5.x, mingw.

Portability problems not fixed by Gnulib:

  * This function cannot work correctly on character strings in most multibyte locales.  Gnulib provides an alternative function mbsstr that works on character strings in all locales.
