* 21 Nov 01 - Ann Harrison - Turn off the code in parse_sqlda that
|
|
* decides that two statements are the same based on their message
|
|
* descriptions because it misleads some code in remote/interface.c
|
|
* and causes problems when two statements are prepared.

|
|
* 2002.10.29 Sean Leyne - Removed obsolete "Netware" port
