ECPG and structure declaration

Hello,

why is the following code fragment an error for ecpg ?

---------------------------------------------
EXEC SQL BEGIN DECLARE SECTION;
struct base
{   char  basekey [ 26 ];
};
EXEC SQL END DECLARE SECTION;

struct base b1[10];
struct base *b2;
---------------------------------------------

ecpg gives the error message:
demo.q:5: ERROR: syntax error at or near ";"

Versions:
- ecpg (PostgreSQL 7.3.3) 2.10.0
- Linux scaleo 2.4.18-4GB #1 Wed Mar 27 13:57:05 UTC 2002 i686 unknown

My intention is to declare the structure type in an include file and
define arrays, pointers, etc from the declaration in various .c files.

What's wrong ?

Cheers,

Jürgen

Because the struct is not used to define a variable.

The next release will be able to correctly parse this kind of definition
itself, but until then you have to list the whole struct definition
when defining the variable.
