COMPILE_OPTION {SQLITE_RTREE_INT_ONLY} {
If this option is used together with [SQLITE_ENABLE_RTREE] then the
[rtree | R*Tree extension] will only store 32-bit signed integer
coordinates and all internal computations will be done using integers
instead of floating point numbers.
}
COMPILE_OPTION {SQLITE_ENABLE_STAT2} {
This option used to cause the [ANALYZE] command to collect
index histogram data in the <b>sqlite_stat2</b> table. But that
functionality was superceded by [SQLITE_ENABLE_STAT3] as of
SQLite version 3.7.9. The SQLITE_ENABLE_STAT2 compile-time option
is now a no-op.

}
COMPILE_OPTION {SQLITE_ENABLE_SQLLOG} {
This option enables extra code (especially the [SQLITE_CONFIG_SQLLOG]
option to [sqlite3_config()]) that can be used to create logs of all
SQLite processing performed by an application. These logs can be useful
in doing off-line analysis of the behavior of an application, and especially
for performance analysis. In order for the SQLITE_ENABLE_SQLLOG option to
be useful, some extra code is required. The
<a href="http://www.sqlite.org/src/doc/trunk/src/test_sqllog.c">"test_sqllog.c"</a>
source code
file in the SQLite source tree is a working example of the required extra
code. On unix and windows systems, a developer can append the text of the
"test_sqllog.c" source code file to the end of an "sqlite3.c" amalgamation,
recompile the application using the -DSQLITE_ENABLE_SQLLOG option, then
control logging using environment variables. See the header comment on
the "test_sqllog.c" source file for additional detail.
