Well, I installed the patch and I'm still getting FAILED errors for the  
GNU Fortran checks (#66 and #67).

As I also explained in a previous e-mail on October 27th the FAILED  
status for these checks does not come directly from the freeform tests  
but from autoconf trying to pass --version to the fort77 script (the  
fort77 script does not accept this option) and autoconf concluding that  
its assumption on fort77 being a GNU compiler must have been incorrect.

The way to go forward depends on which compilers should be considered  
GNU Fortran 77. If this is only appropriate for the g77 compiler or  
compilers that accept similar command line parameters, then we should  
make sure the fort77/fc combination is not recognized as being a GNU  
compiler. This can be done, for example, by including the 'fort77  
--version | grep GNU' check in the macro that determines whether fort77  
is a GNU compiler or not.
If, on the other hand, you would like the fort77/fc combination to be  
tagged as GNU compiler (since it is using gcc underneath), then the  
'fort77 --version | grep GNU' should be removed, since fort77/fc does  
not recognize this option (it uses -v).

Here is the relevant part of the testsuite.log for the patched  
autoconf-2.57g:
