The error happens deep in non-FreeTDS code and seems to have something to
do with locale.  FreeTDS was developed with GNU's libiconv.  If AIX's is
very different (Solaris's is), you might be in for some surprises.  

I would configure --without-libiconv for now and see if that helps.  If it
does and you need more than basic iconv support, I'd look at the GNU
implementation unless you want to muck with the guts of encoding
conversion in FreeTDS.
