The above code is "supposed" to be legal. However, I seem to recall the
HP/UX compiler having an issue with it, too (saw it with a mod_dav report a
long while back).

I can fix it up, and we probably should throughout the code, since I think
you won't be the only person to run into it. Please report them whenever you
smack into them, and we'll get it patched up.

The above code is not legal. You can only do structure initialization at
declaration time.
