Bug 319778 has replaced MySpell with Hunsell. MySpell is no longer built: http://mxr.mozilla.org/seamonkey/source/extensions/spellcheck/Makefile.in#50 Dead code is bad code, so let's get rid of it. Scott, are you OK with that?
Yeah, I've got this in my tree as part of 319778 but haven't had time to check it in yet. Will try to get to it today.
I've removed myspell from extensions\spellcheck.
Could you also remove extensions/spellcheck/locales/en-US/myspell/ ? We now have extensions/spellcheck/locales/en-US/hunspell/ instead. http://mxr.mozilla.org/seamonkey/source/extensions/spellcheck/locales/en-US/myspell/ http://mxr.mozilla.org/seamonkey/source/extensions/spellcheck/locales/en-US/hunspell/
Filed bug 403347 on removing the myspell dictionary from the tree.
