This might turn out to be the best answer.  In effect, TDSICONV would hold
an "error mask" of messages to suppress.  tds_iconv() would add to the mask
as messages accumulated.  The problem would be to remember to clear the mask
when done.  

tds_iconv.h:
        struct _suppress {
                unsigned int ei2big:1;
                unsigned int eilseq:1;
                unsigned int einval:1;
        } suppress;
        /* ... */

/* caller: */
        memset(&iconv_info->suppress, 0, sizeof(iconv_info->suppress));
        iconv_info->suppress.eilseq = *wire_size > 0;
        irreverisible = tds_iconv(...);

I don't know if this is important.  It might be just as easy to call
iconv(3) instead.
