dear all:

if the test fail.
maybe I should choose Explicit linking  by loadLibrary,GetProcAddress 
function in

    Package body XXX
     begin
            -----start loadLibrary and GetProcAddress...
    end XXX;

but It's not so friendly...





<complain>
    off the topic...
    in MS-windows environment,sometime gcc(not ada) make me confused.
    why ld.exe can not link .lib format directly?
    I must say those problems will effect someone learning ada and 
misunderstand it.
</complain>
