It is virtually impossible to link a 32 bit library into a 64 bit product.
 As an example a 64 bit pointer can't be passed to 32 bit code since it
won't fit.

SQLite works just fine in 32 or 64 bits.  And either endian.  And on lower
end platforms.  And on stonking big machines.  Here is the reason why:

  http://www.sqlite.org/testing.html

That page doesn't mention the different hardware SQLite is tested on, but
it is quite a variety and takes a long time.

It works just fine built in 64-bit mode.
