-# If your system doesn't support multi-byte functions (specifically
-# setlocale(), wcwidth(), putwchar()), then remove -DUSE_CHAR. You'll
-# still be able to use -Tlocale, but it becomes a synonym for -Tascii.
+# IFF your system supports multi-byte functions (setlocale(), wcwidth(),
+# putwchar()) AND has __STDC_ISO_10646__ (that is, wchar_t is simply a
+# UCS-4 value) should you define USE_WCHAR. If you define it and your
+# system DOESN'T support this, -Tlocale will produce garbage.
+# If you don't define it, -Tlocale is a synonym for -Tacsii.
