I've also come across this. I first thought it's a GNU vs. something other issue. But gcc proves me wrong. The basic difference is whether a long option has to have two dashes. If it doesn't, then bundling of short options cannot be supported as Mike Wey pointed out some time ago. I often use this bundling when using tar, e.g. tar -xf <file>. Maybe the above tools need no bundling. Jens
