| 18:22 | Add detection of the isnan() library function to the configure script. Make the code responsive to the HAVE_ISNAN configuration option. (check-in: 46f3aba269 user: drh tags: trunk) | |
| 18:02 | Make use of the fdatasync() interface if the HAVE_FDATASYNC macro is true. (check-in: 694228e463 user: drh tags: trunk) | |
| 16:49 | Improvements to compile-time-option hygiene. Use "#if OPTION" instead of "#ifdef OPTION" in cases where that makes sense, so that -DOPTION=0 will work. Add the "Have-Not" configuration in releasetest.tcl which disables all of the "HAVE_component" compile-time options. (check-in: 9e92a5ed5a user: drh tags: trunk) | |
