Ok, then we can rule out a few assumptions. I have a glibc 2.2.4 box here
myself and I've never experienced that problem on that machine... It runs
kernel 2.4.18 though. I also have a glibc 2.1.3 installation that I regularly
runs and tests curl on that works fine (running both 2.4 and 2.6 kernels).

Right, that's probably not relevant anyway.

Uh, does any other name resolves work with curl on this box? Does name
resolves work with other tools?

Not many. You *can* run configure --disable-thread to prevent curl to attempt
to use the thread-safe gethostbyname_r() function and instead use the
traditional gethostbyname() instead. But that breaks the "thread-safetyness"
in libcurl.

Speaking of older versions. Can you get _any_ version of curl to work on your
host? (I mean without the --disable-thread trick)
