+        Use C99's INFINITY and NAN macros
+        * lread.c: Include <math.h>.
+        (string_to_number): Use INFINITY and NAN rather than rolling our own.
+        This avoids some runtime diagnostics when building with
+        gcc -fsanitize=undefined.

         Fix bidi_explicit_dir_char undefined behavior
         * bidi.c (bidi_explicit_dir_char): Avoid subscript error when
         argument is BIDI_EOB.  This can happen in bidi_level_of_next_char.
