    why do you do this? if its not available on apple, it will simply not be found and everything is fine, no? it's optional after all?



debuggers/gdb/stty.cpp
<https://git.reviewboard.kde.org/r/120510/#comment47500>

    why the change here and below (away from < 0)?

In order not to duplicate more code than necessary I changed the logic of `ptyfd`'s initial value slightly, allowing to distinguish between uninitialised and error return values.

Once that's done, the debugger component starts correctly, and appears to communicate with the gdb ("ggdb") slave process up to the point where the GUI is loaded and seemingly ready to go.
