Our current implementation is pretty old and uses some pre-standard/old ANSI C style that triggers warnings like: warning: call to function 'MD5_Init' without a real prototype [-Wunprototyped-calls] This is caused by declarations specified in a following way: src/md5.h:60:6: note: 'MD5_Init' was declared here void MD5_Init (); Having these warnings makes it harded to notice real problems. We could try hiding them but it makes more sense to just use a cleaner code. Another tiny gain from this switch is slightly reduced binary size, on x86_64 tplink-safeloader's size 48104 became 48003. The new code is public domain, uses "heavily cut-down BSD license". Signed-off-by: Rafał Miłecki <rafal@milecki.pl>
