Description
In libmpi.c, MPI_Request is defined as follows:
typedef struct MPIX_Comm_Record {
int id;
} MPIX_Comm_Record;
typedef MPIX_Comm_Record *MPI_Request;
After that I want do say this, but it does not parse:
MPI_Request MPI_REQUEST_NULL = (MPI_Request)NULL;
but this does:
MPI_Request MPI_REQUEST_NULL = (MPIX_Comm_Record*)NULL;

The problem was caused by a bug in the grammar. Casts in assignments were being evaluated as postfix expressions. This was temporarily resolved by moving the rule for casts to the first item under unary_expr. This should probably be changed to match the C grammar.
