The Compaq CC compiler (V6.4) has slightly different prototype for strtoll
than does the version with mysql. The difference is not that big and would
not affect to execution but the compiler thinks this as a bad thing and

configure it yourself.

Ken,
When you configured/compiled MySQL, did you use the --with-innodb option?
What version of MySQL are you running?
