ecpg: dtime_t vs timestamp

We have upgraded from Version 7.4.x to Version 8.2.4.

In 7.4.x, we use the Informix compatibility functionality to use legacy
code.

Our .pgc code looks as follows:

#include "Ice.h"

EXEC SQL include sqlda;
EXEC SQL include sqltypes;
EXEC SQL include sql3types;
EXEC SQL include pgtypes_timestamp;
EXEC SQL include pgtypes_date;
EXEC SQL include pgtypes_interval;
EXEC SQL include pgtypes_numeric;

EXEC SQL BEGIN DECLARE SECTION;
struct Ice_t
{
char lid[9];
char pe[3];
short dur;
char ts[3];
char extremum[2];
dtime_t obstime;
double value;
char shef_qual_code[2];
long quality_code;
short revision;
char product_id[11];
dtime_t producttime;
dtime_t postingtime;
}

The Ice.h header file includes the postgres datetime.h header file. The
datetime.h file has the line "typedef timestamp dtime_t". Using Version
7.4.x, this worked. Now when we use Version 8.2.4 (which has an updated
ecpg), this results in the message

ERROR: invalid datatype 'dtime_t'

How should we fix this?
