** Make sure we can call this stuff from C++.

** program using one of these routines. 
**
** The first argument "db" is an [sqlite3 | SQLite database handle] 
** obtained from a prior call to [sqlite3_open()] or [sqlite3_open16()].
** The second argument "zSql" is the statement to be compiled, encoded
** as either UTF-8 or UTF-16.  The sqlite3_prepare() and sqlite3_prepare_v2()
** interfaces uses UTF-8 and sqlite3_prepare16() and sqlite3_prepare16_v2()
** use UTF-16.
**
** If the nByte argument is less
** than zero, then zSql is read up to the first zero terminator.  If
** nByte is non-negative, then it is the maximum number of 
** bytes read from zSql.  When nByte is non-negative, the
** zSql string ends at either the first '\000' character or 
** until the nByte-th byte, whichever comes first.
**
** *pzTail is made to point to the first byte past the end of the first
** SQL statement in zSql.  This routine only compiles the first statement
** in zSql, so *pzTail is left pointing to what remains uncompiled.
**
** *ppStmt is left pointing to a compiled 
** [sqlite3_stmt | SQL statement structure] that can be

** returned immediately.
