I think that's more or less what the current v3 does, but Jelte's
point (which is upthread for me but downthread for others :D) is that
making them identical might not actually be a desirable thing in this
situation, because if you don't compile --with-libcurl, when you test
that the feature is disabled you might potentially find that it is
not.

This sounds like a pretty decent, simple way to go. Christoph, does
that ring any alarm bells from your perspective?

Thanks,
