They are not supposed to *define* a variable. They are there to tell the compiler not to worry. They are somewhat similar[fn:1] to extern declarations in C code: whoever needs to use the variable says (defvar foo) There is (supposed to be) *one* place somewhere that actually defines it: (defvar foo 1) Nick Footnotes: [fn:1] ...for some value of "similar". You have to take this with the appropriately sized grain of salt.
