re: BEGIN/END DECLARE problems

sorry - i'm using pg 6.4.2, mandrake (RedHat) linux 6.0, pentium

code example that works:

EXEC SQL BEGIN DECLARE SECTION;

struct mouse_s
{
char x[10];
long y;
} mou;

EXEC SQL END DECLARE SECTION;

ecpg is unhappy -"parse error" - if i remove the "mou" declaration, or,
later in my code, try to do:

EXEC SQL BEGIN DECLARE SECTION;
struct mouse_s *mptr;
EXEC SQL END DECLARE SECTION;
