ecpg problem

[Steve Clark <sclark(at)netwolves(dot)com>]

Hello List,

Don't know whether anyone here can help but... We have some code that 
has compiled and ran just
fine from postgresql 7.3.x thru 8.2.6. It uses embedded sql. I just 
yesterday upgraded our test system to
8.3.0 and this code will no longer compile. Below is a standalone code 
fragment in which I have removed
everything but what is causing the problem. Any help or ideas would be 
appreciated.

exec sql include sqlca;

EXEC SQL WHENEVER NOT FOUND CONTINUE;

// this array is grown as messages from new units are received
// it is sorted by unit_serial_no ascending to support binary searches

int getUnitData()
{

    exec sql begin declare section;

        VARCHAR h_unit_serial_no  [ 15+1];
        // we do an array fetch on these 30 is the max number for these
        int     h_remote_int_netmask    [4096];
        int     h_local_int_netmask     [4096];
        VARCHAR h_tunnel_active         [4096][   1+1];
        VARCHAR h_tunnel_config_type    [4096][   1+1];
        VARCHAR h_local_vpn_int_ip      [4096][  20+1];
        VARCHAR h_local_vpn_ext_ip      [4096][  20+1];
        VARCHAR h_remote_vpn_int_ip     [4096][  20+1];
        VARCHAR h_remote_vpn_ext_ip     [4096][  20+1];

    exec sql end declare section;

        exec sql select tunnel_active,
                        tunnel_config_type,
                        host(local_int_gw_ip),
                        host(local_ext_gw_ip),
