.F fix to automake.in

[Christian Holm Christensen]

Dear Automake team, 

First off, thanks for a great piece of software. 

I wanted to make some libraries of Fortran77 code, but I had some
problem with preprocessed Fortran source files.  

I did a bit of tracking, and found that lang_ppf77_rewrite wasn't
defined, and that the subroutine lang_ppf77_finish output errouneous
rules. 

Below is a patch that should fix these problems.  I hope you find it
usefull.  I did this patch against version 1.4 (latest Changelog entry
at 1999-01-14).

If you already have solved this problem, my apologise for bothering
you.   

Yours, 

Christian  -----------------------------------------------------------
