Experimental combination of SQLite 3.3.x and TinyCC 0.9.23 using the new
SQLite loadable extension mechanism. An extension module creates an SQLite
scalar function 'tcc_compile' which takes an argument which is a string
made up of C source code to be on-the-fly compiled using TinyCC
(www.tinycc.org). The SQLite API is visible during compilation when
'sqlite3.h' is included. See the file 'strict_typing.sql' for a working
example.

Caution: So far, only partially tested on Linux i386 and Win32.

Win32 notes: The sqlite+tcc.dll module must be kept in the same path
as the TCC include and lib directories.
