For the record, I know that the documentation says the OMIT_* flags don't work with the regular amalgamation, but I have in fact used many of them and they seem to work. Two that only partially worked (a bug?) are SQLITE_OMIT_AUTOVACUUM and SQLITE_OMIT_AUTHORIZATION (I am not sure about that second one, as I am writing this from memory. I think it was that one) They gave a warning when compiling sqlite3.c and an error when linking it to my program.
