         * configure.in (C_OPTIMIZE_SWITCH, CANNOT_DUMP, SYSTEM_MALLOC):
-        (USE_MMAP_FOR_BUFFERS, C_WARNING_SWITCH): Set with shell, not cpp.
+        (USE_MMAP_FOR_BUFFERS, C_WARNING_SWITCH, CFLAGS, REAL_CFLAGS):
+        Set with shell, not cpp.
         (LIBX): Remove, just use -lX11 in the one place this was used.
         (cannot_dump): Replace with CANNOT_DUMP.
