 Portability problems fixed by Gnulib:
 @itemize
+@item
+The function @code{getopt_long} does not support the @samp{+} flag in
+the options string on some platforms:
+MacOS X 10.5, AIX 5.2, OSF/1 5.1, Solaris 10.
+@item
+The function @code{getopt_long} does not obey the @samp{-} flag in the
+options string when @env{POSIXLY_CORRECT} is set on some platforms:
+Cygwin 1.7.0.
+@item
+Some implementations fail to reset state, including re-checking
+@env{POSIXLY_CORRECT}, when @code{optind} is set to @samp{0}:
+NetBSD, Cygwin 1.7.0.
+@item
+The function @code{getopt_long} does not support options with optional
+arguments on some platforms:
+MacOS X 10.5, OpenBSD 4.0, AIX 5.2, IRIX 6.5, Solaris 10, Cygwin 1.5.x.
+@item
+This function is missing on some platforms:

-This function is missing on some platforms:

+The glibc extension of using @samp{W;} in the optstring argument to
+allow @code{-W foo} to behave synonymously with @code{--foo} is not
+very reliable, even in glibc.
