Getting the TAB key for filename completion

[Davin Pearson]

I have installed hippie-expand inside my Emacs.  Specifically I have

installed the following command:



(fset 'my-complete-file (make-hippie-expand-function

                         '(try-complete-file-name-partially

                           try-complete-file-name)))



My trouble is that I cannot bind this command to the TAB key when you

enter the command M-x compile RET.  Could someone please advise me how

to get file name completion with the TAB key online?
