+/* If you are using SunOS 4.1.1 and X11r5, then you need this patch.
+   There is a stupid bug in the SunOS libc.a: two functions which X11r5
+   uses, mbstowcs() and wcstombs(), are unusable when programs are
+   statically linked (as Emacs must be) because the static version of
+   libc.a contains the *dynamic* versions of these functions.  These
+   functions don't seem to be called when Emacs is running, so it's 
+   enough to define stubs for them.
+
+   This appears to be fixed in SunOS 4.1.2.
