Problem importing schema.sql

I'm trying to import schema.sql but...

#1171 - All parts of a PRIMARY KEY must be NOT NULL; if you need NULL in a key, use UNIQUE instead

Hello, thanks for reporting
Are you using mysql 5.7.3 ? Seems a breaking change in the last version..

@MBoretto I'm using 5.7.11 but I've seen a fix in structure.sql

Replacing all NULL in Primary Keys by NOT NULL.
