Why present different size and md5 hash between the compiled code and FreeBSD's build-in binary ?

[Jerry]

Hi~

This is my first time to post question here, and also
I am a newbie on FreeBSD. A confusing thing I discover
is: Why the binary code I compiled(for example,telnet
command)compare with the original one is diffirent,
either size or md5 hash value, What's going on? Are
the source files differ from the FreeBSD's binary, or
something else ?
Deeply appreciate your reply, thanks ~
