Hm, the symbol 'curl_jmpenv' only has one definition in libcurl.

I have two work-arounds coming up:

Short-term: I'm gonna move the sigjmp_buf stuff to only get used within a
single source file, and then I can make it a static, which will be nicer to
all parties.

Long-term: I'm gonna put on effort on providing a reliable non-blocking name
resolver which will then remove the need for that longjmp() stuff entirely.
(More about that will follow in a later mail.)
