At least in Qt 4.4 -- the last I studied extensively, as someone else has done 
the Solaris 4.5 port this week -- it would go looking for GNU iconv or other 
iconv and the difference is hidden in QTextCodec. If there's iconv, an 
additional .so is produced and codecs behave as plugins; otherwise a number 
of codecs are compiled in to QtCore.

So up until recently it did work. You don't say what the nature of "behave" is 
though -- does it not compile? Not run?

The traditional difference is 

       size_t iconv(iconv_t cd,
                    char **inbuf, size_t *inbytesleft,
                    char **outbuf, size_t *outbytesleft);

in some implementations (UNIX98 standard?), inbuf is a const char **.
