Fix nob's program name on windows

[Notxsomeone]

Although executable on windows end with .exe they can be called without them. This makes argv[0] different from the actual name of the program (nob.exe) and causes MoveFileEx to fail.

As of my understanding you are never breaking out or the loop. Are You?

while(0) technique is used everywhere and it only runs once. I don't know what are you talking about.

My apologies I overlooked while(0).
But is using a single interactional loop advantageous by any change.Just a question from my side

It makes the entire macro act like a statement, meaning you have to put a semicolon at the end plus it has its own scope so no conflicts if you call it multiple times.
If I really wanted to be pedantic it would have been nice to surround argv with parentheses so expressions get evaluated, but that's a very unusual use case for argv (you are supposed to just pass it as it is) so whatever. Classic C macros and its shenanigans.
