The following patch should fix 'date -R' to use English for the date
(as per RFC 822):

--- date.c.old	Mon Jan 11 01:24:05 1999
+++ date.c	Mon Jan 11 01:27:05 1999

+  if(rfc_format)
+    setlocale (LC_ALL, "C");
   do
     {
       out_length += 200;
       out = (char *) xrealloc (out, out_length);
     }
   while (strftime (out, out_length, format, tm) == 0);
+  if(rfc_format)
+    setlocale (LC_ALL, "");
 
   printf ("%s\n", out);
   free (out);

The only (slight) bug is that if xrealloc or strftime fail the failure
message will be in English.
