Yes you have to get up early … 😮
I do not think it is the time that matters!
We will need to know:
1) With what program was that dump generated? 'mysqldump' ?
2) From what MySQL version?
3) To what version do you try to import ?
4) SQLyog program version?
Pease try 5.22 RC1. It should handle 'version dependent conditional comments' (/*!40103 … */) correctly.
If you still have an issue, please post a (small) test case to reproduce with.
