Subject: Re: Dillo gopher plugin on OpenBSD issue
[...]
Somehow I missed it seeing there was a list. I found another
issues with the gopher plugin on OpenBSD.
The issue I am testing is with dpi.c. On OpenBSD, it has to
do with how clang works on OpenBSD. The diffs are below.
So far, with the changes to io.c and dpi.c, the plugin
works fine on both OpenBSD and NetBSD.
