Such K&R way to declare functions sounds like an open invitation for

C++ complains if function was declared K&R style and used correctly.
So I had to change those declarations in tcpd.h to compile correctly.

Yes, please add them! Right now MySQL calls functions the wrong
way but due to the specifics of i386 assembly they get away with this.
Since compiler pushes this argument to stack before calling
them for some function following later on. So they use it as if it
was theirs )) And Alpha code is built differently so this bug comes up.
