Error binding boolean data type to SQL_C_CHAR

The attached program accepts 3 parameters:

1. The ODBC DSN
2. The database user name
3. The database password

It then connects to the database, creates a simple table that has a bool and attempts to bind and populate.
You will see that the only binding failure is SQL_C_CHAR.
The exact error message is:
check_error> SQL_ERROR
return code = -1 reported from file: bugg.cpp, line: 232
SQLSTATE: 22001
