Options

1) Fix bug on strange sprintf 

2) Fix bug on bad sprintf
3) Fix bug on cast from pointer to int

4) Begin implementing the "info" tables.
Already existing were the ODBC sata source table and the
WMI column info table.

A common way to handle them will permit to develop many
other such tables. Implemented:

The ODBC column info table.
