Version 1 Calling convention

I have a .pgc file and i have the following code snippet in it:

PG_FUNCTION_INFO_V1 (test);

Datum
test (PG_FUNCTION_ARGS)
{
  EXEC SQL BEGIN DECLARE SECTION;
           int id = PG_GETARG_INT(0);
           char *raw_rawemail1 = PG_GETARG_CHAR_P(1);
           char *rawemail1 = (char *)  palloc (VARSIZE(rawemail1));
           VARATT_SIZEP ( rawemail1 ) = VARSIZE (raw_rawemail1); //LINE 140 (thats where i get syntax error)
           memcpy( (void *) (VARDATA) (rawemail1), (void *) (VARDATA) (raw_rawemail1) , (VARSIZE) (raw_rawemail1) - VARHDRSZ );
  EXEC SQL END DECLARE SECTION;

  EXEC SQL CONNECT TO dbxyz;
}

When I compile this using
ECPG parser.pgc

I get the follwing error

Syntax error at or near 'rawemail1' (LINE 140 marked above)

Don't know what this error is all about.
Don't know if my declaration in BEGIN END block is correct in the pgc file for version 1 calling convention

Thanks
