the 'rtreeUpdate' function plays an absolutely
strategic role, because it manages R*Trees,
i.e. the Spatial Index key component.
please note: while building SQLite you MUST define
some macro defs in order to enable some 'advanced'
features subject to conditional compilation.
-------
LARGE_FILE=1
FILE_OFFSET_BITS=64
LARGEFILE_SOURCE=1
the above defs are required if you wish to
enable support for arbitrary size DBs: if you
omit them a 32-bit system will be unable to
handle any DB exceeding 2GB.
Please note: this is surely true for Win32,
Linux, MacOsX [and any other Unix-like], but
I completely ignore if this is required/supported
on WindowsCE / WindowsMobile
---------
SQLITE_ENABLE_RTREE=1
this is required in order to enable RTree aka
Spatial Index (RTree is strictly required in
order to fully support SpatiaLite)
