Hi, Mike!

I'm looking at this and previous bug (https://bugs.x2go.org/777) and can't stop wondering
whether applications should really contain workarounds for bugs in
system libraries. Isn't it better to just depend on newer version
of library (that has fixes for currently known bugs)?

There are a lot of older bugs in glibc (that are fixed in current
version), does it mean that applications should be bloated with
workarounds for such bugs just in order to work more safely on machines
where users don't pay enough attention to updates?

That is a true way of reasoning...

However, gethostbyname is deprecated in glibc and not really IPv4/IPv6
compliant [1].
