+Subject: [PATCH] erts/emulator: reorder inclued headers paths
+
+If the Perl Compatible Regular Expressions is installed on the
+host and the path to the headers is added to the CFLAGS, the
+pcre.h from the host is used instead of the one provided by
+erlang.
+
+Erlang use an old version of this file which is incompatible
+with the upstream one.
+
+Move INCLUDES before CFLAGS to use pcre.h from erlang.
