As nice at it sounds, migrating to posix_spawn() doesn't sound necessary right now to resolve build or runtime support for Windows-based platforms, at least not relative to curing regressions from the level of support we had in groff 1.22.4. But it's a good idea, if not obviated by the tbl(1) work I mentioned, so I have filed https://savannah.gnu.org/bugs/?64055 about it. Regards, Branden
