3-pg85-describe-17-ctxdiff.patch (text/x-patch) patch

Hi,

new patch is attached. Modified according to
the new DB2 / Sybase compatible SQLDA structure.
ECPGdescribe() has an "int compat" parameter, because:
- the (struct prepared_statement *)->stmt ->compat is not set, and
- it's more sensible to use the compat mode of the
  ECPGdescribe() caller, because different source files can be
  compiled with different (native or compat) modes.
The Informix-specific syntax "DESCRIBE ... INTO sqlda" is also
accepted in native mode now.

Best regards,
Zoltán Böszörményi
