2-pg85-sqlda-19-ctxdiff.patch (text/x-patch) patch

Hi,

new patch attached.

Per Michael's request, a DB2 / Sybase compatible
SQLDA structure is implemented for ECPG's native mode.
The Informix-compatible structure is only for compat mode.
The sqlda.h header switches between the two different
structures depending on a new #define introduced in
and added to the generated C source by the preprocessor
in compat-mode. Also, per discussion with Michael,
     FETCH ... USING DESCRIPTOR sqlda
is also accepted by the grammar in native mode, too.

Best regards,
Zoltán Böszörményi
