+
+libsiconv can/will use libc iconv if it knows about a particular
+character set (or pair thereof), and will fall back to its own
+implementation and tables otherwise. glibc fails to offer the
+"cp10000" identifier, but it does have the desired table under a
+different name.
+
+Change the name in .c so we do not need to install the cp10000 siconv
+table.
 
-Workaround a shortcoming in glibc which lacks cp1XXX identifiers
-without having to install any siconv tables.
