I compiled SQLite 3 (version 3.5.7), specifying
SQLITE_OMIT_TRIGGER to reduce the size of the
generated code.
I got the following compilation warnings in
parse.c:
-------------------------------------------------------------------------------------------------

-------------------------------------------------------------------------------------------------
The various trigger functions are declared in
sqliteInt.h as follows:
-------------------------------------------------------------------------------------------------
#ifndef SQLITE_OMIT_TRIGGER
void sqlite3BeginTrigger(Parse*, Token*,Token*,int,int,IdList*,SrcList*,
Expr*,int, int);
void sqlite3FinishTrigger(Parse*, TriggerStep*, Token*);
void sqlite3DropTrigger(Parse*, SrcList*, int);
void sqlite3DropTriggerPtr(Parse*, Trigger*);
int sqlite3TriggersExist(Parse*, Table*, int, ExprList*);
int sqlite3CodeRowTrigger(Parse*, int, ExprList*, int, Table *, int, int,
int, int, u32*, u32*);
void sqliteViewTriggers(Parse*, Table*, Expr*, int, ExprList*);
void sqlite3DeleteTriggerStep(TriggerStep*);
TriggerStep *sqlite3TriggerSelectStep(sqlite3*,Select*);
TriggerStep *sqlite3TriggerInsertStep(sqlite3*,Token*, IdList*,
ExprList*,Select*,int);
TriggerStep *sqlite3TriggerUpdateStep(sqlite3*,Token*,ExprList*, Expr*, int);
TriggerStep *sqlite3TriggerDeleteStep(sqlite3*,Token*, Expr*);
void sqlite3DeleteTrigger(Trigger*);
void sqlite3UnlinkAndDeleteTrigger(sqlite3*,int,const char*);
void sqlite3SelectMask(Parse *, Select *, u32);
#else
# define sqlite3TriggersExist(A,B,C,D,E,F) 0
# define sqlite3DeleteTrigger(A)
# define sqlite3DropTriggerPtr(A,B)
# define sqlite3UnlinkAndDeleteTrigger(A,B,C)
# define sqlite3CodeRowTrigger(A,B,C,D,E,F,G,H,I,J,K) 0
# define sqlite3SelectMask(A, B, C)
#endif
-------------------------------------------------------------------------------------------------
It would seem that, in the #else section, we just need to
add 9 more no-op macros for the undefined trigger functions.
