** Fix build problem when scm_t_timespec is different from struct timespec
** Fix build when compiled with -Wundef -Werror
+** Allow @ macro to work with (ice-9 syncase)
+
+Previously, use of the @ macro in a module whose code is being
+transformed by (ice-9 syncase) would cause an "Invalid syntax" error.
+Now it works as you would expect (giving the value of the specified
+module binding).
