using PHP doesn't help in pure C++ desktop applications that do not run in
web-server entironments.

The PHP library IS the translation layer.

The crux of the issue is that the formats are NOT compatible, nor are 
the API's. What Dr. Hipp suggested is the best possible course. Link 
with both API's which _DO_ have separate naming conventions making it 
possible to support both formats concurrently. All new databases follow 
Sqlite3, legacy follow Sqlite2.

There are signatures in the database files to distinguish between the 
two. Use the tools that are available to add the layer of abstraction 
necessary. Don't force that on SQlite itself.

Its all summed up in one sentence, which is the first one that appears 
at sqlite.org:

"SQLite is a small C library that implements a self-contained, 
embeddable, zero-configuration SQL database engine."

The focus is there, anything beyond that is up to the implementation.
