It seems that Sys.commd always returns 0 on Windows 98 (even if the 
command does not exist) ?
(it works on XP and Linux).

Is this a Bug or a Windows 98 limitation ?

re about the previous loop's allocations:
>>
>>for(i=0;i<n;++i) {
>>   CAMLlocal(foo,bar);
>>   // use foo bar
>>   // callback to caml with foo bar, maybe somebody stores them somewhere
>>   CAMLendblock();  // want this
