paps-c99.patch

+Use AC_USE_SYSTEM_EXTENSIONS and include <config.h>, so that <wchar.h>
+makes a declaration of wcwidth available.  Include <glib/gprintf.h>
+for a declaration of g_vasprintf.  This avoids implicit function
+declarations and build failures with future compilers.
+
+No need to upstream this because it only impacts the bundled 0.6.8
+sources, the later 0.8.0 version has already been fixed upstream.  The
+g_vasprintf call was introduced in the paps-0.6.6-lcnumeric.patch
+downstream patch.
