I assume that you also put (savehist-mode 1) in your .emacs.

If `compilation-read-command' is non-nil (the default value is t) then
"make -k" is always the default value for the compile command. To have the
default value for the compile command be the last compile command you
entered, set `compilation-read-command' to nil.
Check the value of variable `compile-history' after step 2, using `C-h v'.
If it includes the last compile command you entered, then the problem is not
with savehist. In that case, you might want to report an Emacs bug for
command `compile'.

It's the variable that tells savehist where you want to save the histories.
By default, its value is "~/.emacs-history". You can customize this
variable.
In sum, check the saved value of `compile-history'. If it looks good, then
the problem is not with savehist.
