The last commited changes have brought important additions to CONNECT.
1 - Replacement of setjmp/longjump's by try/catch/throw
2 - Support of multiple tables in subdirectories
3 - Support translating ENUM to VARCHAR for MYSQL tables.
4 - Tables based on ZIP files

Support ENUM data type for MYSQL tables.
