+@code{j}, @code{t}, @code{z}) on some platforms:
+AIX 5.1, HP-UX 11.23, IRIX 6.5, OSF/1 5.1, Solaris 9, Cygwin 1.5.24, mingw, BeOS.
+@item
+printf of @samp{long double} numbers is unsupported on some platforms:
+mingw, BeOS.
+@item
+printf @code{"%f"}, @code{"%e"}, @code{"%g"} of Infinity and NaN yields an
+incorrect result on some platforms:
+AIX 5.2, OSF/1 5.1, Solaris 10, mingw.
+@item
+This function does not support the @samp{a} and @samp{A} directives on some
+platforms:
+glibc-2.3.6, MacOS X 10.3, NetBSD 3.0, OpenBSD 4.0, AIX 5.2, HP-UX 11,
+IRIX 6.5, OSF/1 5.1, Solaris 10, Cygwin 1.5.x, mingw, BeOS.

+This function does not support the @samp{ls} directive on some platforms:
+OpenBSD 4.0, IRIX 6.5, Solaris 2.6, Cygwin 1.5.x, Haiku.
+@item
+This function does not support precisions in the @samp{ls} directive correctly
+on some platforms:
+Solaris 10.
+@item
+This function does not support format directives that access arguments in an
+arbitrary order, such as @code{"%2$s"}, on some platforms:
+NetBSD 3.0, mingw, BeOS.
+@item
+This function doesn't support the @code{'} flag on some platforms:
+NetBSD 3.0, Cygwin 1.5.24, mingw.
+@item
+This function behaves incorrectly when a @samp{-} flag and a negative width
+are specified together, on some platforms:
+HP-UX 10.20.
+@item
+printf @code{"%010f"} of NaN and Infinity yields an incorrect result (padded
+with zeroes) on some platforms:
