Anyhow, these are the testsuite results with the broken hand
implementation ;-)  (I will try your patch Andrey, thanx a lot).

Notice that all fails on libio and libstdc++ are on strings, which I
cannot help but correlate to the fact that nm could not operate on the
instantiation file for the string class, so nm pic/cstrmain.o returns 
pic/cstrmain.o: 0654-206 Cannot process the symbol table.  
I guess the patch correctly gets all symbols.

Just my 2 cent tip,
