Guix QA review form submission:
I was able to build the updated package without issue and view a .fst
file.

We may want to update the package homepage and repo URL at some point,
as it seems to be moving away from sourceforge and to github
(see: https://github.com/gtkwave/gtkwave/issues/320). It does look 
like the sourceforge page is still getting the lastest versions
released to it first right now.
