-From cfc5e509f6a7403771a5a8aa27120fccd6718784 Mon Sep 17 00:00:00 2001
-From: "Richard W.M. Jones" <rjones@redhat.com>
-Date: Tue, 17 Feb 2015 15:22:23 +0000
-Subject: [PATCH] lib/io.h: Use uint32_t from stdint.
-
-In OCaml > 4.02, the caml/*.h headers no longer define illegal types
-such as uint32.  See this link for rationale:
-http://caml.inria.fr/mantis/view.php?id=6517
-
-Therefore you can't rely on these types being available in code using
-these header files any longer.
-
-Change the gsl code to use the C99 standard header <stdint.h> and the
-uint32_t type instead.
