Yes, I've seen that. I was suggesting to go back to the situation prior to
r22534, when ifaddrs.h was installed, and not reverting its content.
Sorry for the confusion...

Well, I'm not quite confortable with that: it's dependent on a config option,
we build it, it's in the libc.so, but noone should use it?

Anyway, we've got one user at least: the Java frontend from gcc-4.3.1.

The whole .h file should be guarded with __UCLIBC_SUPPORT_AI_ADDRCONFIG__
and processed through unifdef to remove its content if uClibc is not
configured as such. Or better yet, there are a bunch of includes that get
removed at install time. Let's add one more.

Will check tomorrow. Will keep you informed.

Right, sorry again...

Well, you know those autotools stuff: they try to include the header file,
then they define a prototype and try to link, and if the latest works
although the former does not, they conclude that they can use it.
