Since most programs internally allocate a buffer of size MAX_PATH or
PATH_MAX, they won't have enough room to store the full filename. Tt would
certainly be possible to support this if a system call was made with a long
filename, but that would mean replacing all statically allocated path
buffers (e.g. char buf[MAX_PATH]) with alloca (e.g. char *buf = alloca
(strlen(inbuf) + margin)) which is more than trivial.
