mistachkin 60e0807801 Add SQLITE_DISABLE_INTRINSIC define to disable use of intrinsic functions (e.g. for certain older compilers and/or platforms).

drh 3bc3709e7b Restore an undocumented side-effect of PRAGMA cache_size: it forces the 
database schema to be parsed.  Also increase the version number to 3.8.11.1.

drh 8ea60e35c2 The "PRAGMA cache_size" reads the database schema, as it has down in all prior 
versions of SQLite.  This side-effect of cache_size is undocumented, but 
apparently it does get used and its absence from 3.8.11 was causing problems.

lands in the wrong register.  Fix for ticket [8fd39115d8f46ece70e7d4b3].
