Rework the code in ctime.c a bit to report on more compile time options. And to only output configuration options passed in to SQLite, not the default values of #define symbols set automatically. Also generate the large array in ctime.c using new script tool/mkctime.tcl, instead of entering it manually. check-in: 9a443397 user: dan tags: trunk
