   2 ** If the canonical build process finds the file
   3 ** sqlite3_wasm_extra_init.c in the main wasm build directory, it
   4 ** arranges to include that file in the build of sqlite3.wasm and
   5 ** defines SQLITE_EXTRA_INIT=sqlite3_wasm_extra_init.
   6 **
   7 ** The C file must define the function sqlite3_wasm_extra_init() with
   8 ** this signature:
   9 **
  10 **  int sqlite3_wasm_extra_init(const char *)
  11 **
  12 ** and the sqlite3 library will call it with an argument of NULL one
  13 ** time during sqlite3_initialize(). If it returns non-0,
  14 ** initialization of the library will fail.
