To be concrete: take as example BOOLEAN datat type:

Firebird 3.0:
#define SQL_BOOLEAN                32764 // new in Firebird 3.0
#define SQL_NULL                         32766 // new in Firebird 2.5

Interbase 7.0 (For ESQL and DSQL programmers, we define the following 
type in ibase.h:):
#define SQL_BOOLEAN 590 ... ;-))

So how we should update ibase60.inc ?
and support both in one TIBConnection ... I expect, that data will be in 
both cases as 0/1 signed short ) ... it seems to me easier!

Or split header files ... but then we must also create TFBConnection 
(like TIBConnection) ? ... it seems to me more complicated ATM
