.dic files vary across builds
When working on reproducible builds for openSUSE, I found that our fwnn package varied for every build because .dic files had the current time, build host name and inode numbers in their headers.
I have created a patch to use fixed values instead, but dont know if that will disturb normal operation.
I checked your patch file.
FreeWnn with your patch can not read dictionaries.
So we can not accept your patch.

I wrote a patch.
I wait untill 2019-01-18 (+0900).
If it has no problem, I'm going to commit this patch to the CVS repository.
Please see: https://osdn.net/projects/freewnn/lists/archive/users/2019-January/000320.html
I backported your patch to FreeWnn-1.1.1 and it indeed made the package build reproducible.
So it is very good from my perspective.
I cannot check that it still works, though.
