+[Q28]	``After upgrading to a glibc 2.1 with symbol versioning I get
+	  errors about undefined symbols.  What went wrong?''
+
+[A28] {AJ} In a versioned libc a lot of symbols are now local that
+have been global symbols in previous versions. When defining a extern
+variable both in a user program and extern in the libc the links
+resolves this to only one reference - the one in the library. The
+problem is caused by either wrong program code or tools. In no case
+the global variables from libc should be used by any program. Since
+these reference are now local, you might see a message like:
+
+"msgfmt: error in loading shared libraries: : undefined symbol: _nl_domain_bindings"
+
+The only way to fix this is to recompile your program. Sorry, that's
+the price you might have to pay once for quite a number of advantages
+with symbol versioning.
