Description:
It would be very good if MySQL prints warning message to error log if InnoDB storage engine gets disabled due to different log file size, for example.

Currently you will see in the error log only:

InnoDB: Error: log file ./ib_logfile0 is of different size 0 5242880 bytes
InnoDB: than specified in the .cnf file 0 10485760 bytes!

and only when InnoDB is default storage engine you will message like:

InnoDB: Error: log file .\ib_logfile0 is of different size 0 5242880 bytes
InnoDB: than specified in the .cnf file 0 10485760 bytes!
080430 11:28:41 [ERROR] Default storage engine (InnoDB) is not available

It would be good if server printed warning message that InnoDB storage engine is disabled even when InnoDB is not default.

How to repeat:
1. change innodb_log_file_size
2. restart server
3. check error log
