This function has quadratic instead of linear worst-case complexity on some

platforms:

|
glibc 2.8, MacOS X 10.5, FreeBSD 6.2, NetBSD 5.0, OpenBSD 4.0, AIX

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.
