While compiling for aarch64, the compiler throws the warning below because char is unsigned for aarch64. main.c: In function ‘main’: main.c:145:48: warning: comparison is always true due to limited range of data type [-Wtype-limits] 145 | while((opt = getopt(argc, argv, "dF")) != -1) { | This makes nfsrahead to run forever.
