nvarchar(max) field in result set identified as WVARCHAR, not WLONGVARCHAR

Hi,

When I use SQLColAttributeW(... SQL_DESC_CONCISE_TYPE ...) to ask FreeTDS
for the type of an nvarchar(max) column in my result set, it calls it a
SQL_WVARCHAR (-9). However, when I ask it for the type of an ntext field,
it calls it a SQL_WLONGVARCHAR. Since nvarchar(max) is the replacement for
ntext[1], shouldn't FreeTDS return -10 as the type of nvarchar(max) too?

Thanks,
m.
