When doing that, please consider the scenario where argv[0] does not have a directory part (i.e., does not have a '/' in POSIX). In this case in the past it has been reasonably common for argv[0] to not identify the executable that would be found by searching PATH for a file with that name, either because PATH itself has changed since the parent did the search, or because the program is being executed in a chrooted jail, or for some other reason. If this usage need not be supported by GNU programs it would be helpful to have that clearly stated.
