No. I just fixed it yesterday. :) So the fix is new. I'll probably get it

You can compile yourself a custom version of the sockets unit from current
trunk too in the mean time. Or you can even patch 3.0.4, if you want.
Here's what's changed:


Falling back to inet_pton() is also an option indeed, if your program
already links against libc (for threading or other reasons), that might be
the easiest option.
