Question file for benchmark/robustness/hetero/esql

t2.pc is C program created using Pro*C.  There are a couple of
"normal" parser issues plus the embedded SQL. 

1. There is some information that is missing, such as the
definition of the varchar [] data type and calls to the
sqlca library.  Were there others?

2. There are a number of EXEC SQL statements.  How does your parser
deal with these?

3. There are some SQL scripts included in the test bucket.  Is
any of the information in these files used, for example to
track data?
