Well, if someone wants to do more work for the sake of argument, then I guess we live in a free world. But still, the fonts are such a fringe part of wine that I just can't see any extra work to be worth it. For a while one can just consider fontforge to be a "proprietary" tool, and wine would just ship the sources and resulting fonts. It's just a matter of being practical.
Looks like you are not aware how much pain gcc bugs (like a strength-reduce
We're talking about a couple of fonts and a relatively obscure tool, not about the compiler which compiles the whole wine tree. Comparing fontforge to gcc in the context of this discussion is a long shot to say the least. I'm not trying to say that gcc had no bugs, etc. I'm just arguing for including those silly ttfs in the source distibution, that's all.
