Bug 1460600: Remove unsupported --enable-system-hunspell flag. r=glandium Our bundled Hunspell now significantly differs from upstream Hunspell. Most importantly, it supports loading dictionaries from jar: URIs, which is now a requirement for loading bundled and extension dictionaries. This means that system Hunspell libraries are no longer compatible with our spell checker code. We should remove the option to use them so that users don't fall into the trap of trying to use them.
