This is part of an attempt to modernise Haskell's wxWidgets libraries. See here for context.
This packages the Haskell-agnostic wxc library for Arch Linux, so that wxHaskell can then be installed.
Remember we always need to run makepkg --printsrcinfo > .SRCINFO upon making any changes to PKGBUILD, before committing.
Deploy with git push aur main:master (assuming we have once run git remote add aur ssh://aur@aur.archlinux.org/wxc.git).
