Overview
| Comment: | Fix sqlite3Atoi64 to return true if handed a number of all zeros. The failure to do this is benign as sqlite3Atoi64() is current used, but that might change in the future so it is good to go ahead and fix the function to return the correct result. (CVS 5142) |

| 20:11 | SQLite stores native file names and paths for the database file. Under Windows, (file normalize test.db) is expanded using UNIX type path separators which TCL recognizes interchangeably. However, this means that the path reported by sqlite3_shared_cache_report doesn't match which causes the test case to fail. Made minor change to test case to hopefully correct this on all platforms.
