I probably was not clear. MSEgui has two approaches:

1. transaction.options tao_fake, works for all databases except Firebird which 
does not support implicit transactions.
2. Dataset option dso_offline, works for all databases and probably is 
equivalent to the FPC patch.

1. is important for users who come from Zeos or MySQL users who update from an 
older FPC version where MySQL transactions where not supported (normally they 
switch to Zeos...) or Sqlite3 where explicit transactions sometimes are
