I _think_ I found the problem:
in convert.c in the function copy_and_convert_field, you declare
char tempBuf[TEXT_FIELD_SIZE+5];
wich is fixed at _compile_ time, no ?, so the TEXT_FIELD_SIZE wich
is an option in the Odbc driver cfg, is ignored.
I'm rigth ? (because changing Max LongVarChar in the cfg doesn't
seems to affect nothing)
