+# SYNOPSIS
+#
+#   AX_CHECK_SIGN (TYPE, [ACTION-IF-SIGNED], [ACTION-IF-UNSIGNED], [INCLUDES])
+#
+# DESCRIPTION
+#
+#   Checks whether TYPE is signed or not. If no INCLUDES are specified, the
+#   default includes are used. If ACTION-IF-SIGNED is given, it is
+#   additional shell code to execute when the type is signed. If
+#   ACTION-IF-UNSIGNED is given, it is executed when the type is unsigned.
+#
+#   This macro assumes that the type exists. Therefore the existence of the
+#   type should be checked before calling this macro. For example:
+#
+#     AC_CHECK_HEADERS([wchar.h])
+#     AC_CHECK_TYPE([wchar_t],,[ AC_MSG_ERROR([Type wchar_t not found.]) ])
+#     AX_CHECK_SIGN([wchar_t],
+#       [ AC_DEFINE(WCHAR_T_SIGNED, 1, [Define if wchar_t is signed]) ],
+#       [ AC_DEFINE(WCHAR_T_UNSIGNED, 1, [Define if wchar_t is unsigned]) ], [
+#     #ifdef HAVE_WCHAR_H
+#     #include <wchar.h>
