ECPG error message

Hi all,

When I try to compile source code with these variable declarations:

18 EXEC SQL BEGIN DECLARE SECTION;
19 struct FIELDS_t {
20 char cod[16];
21 long double val;
22 } fields;
23 char command[100];
24 EXEC SQL END DECLARE SECTION;

$ ecpg -t -I /usr/local/pgsql/include -o tstexecute.c tstexecute.ec

I get this error message:

tstexecute.ec:20: ERROR: parse error at or near "double"

What's the problem with long double?
Isn't it a standard C data type?

I'm using PostgreSQL 7.1.2, compiled with options:

--with-tcl --enable-locale --enable-multibyte=LATIN1

and my system is a:

Linux version 2.2.16-13cl ( root(at)mapi2(dot)conectiva(dot)com(dot)br
