Hi,

IIUC it is a pre-requisite for IPv6 support, some UNICes do not support
getaddrinfo required for IPv6.  But coincidentally such UNICes are no longer
really supported by GDB.  Therefore it was concluded we can remove all such
UNICes and then we can implement IPv6 easily with getaddrinfo.

So I chose HP-UX first for this patch.

Not sure if anything should be really done for this part.

I did not test it anyhow, not sure how, it still builds on Linux.

I did not investigate too much which other parts of GDB could be removed
along, there may be some dead code now (but it always has been).

I am not sure if somread.c really can be removed or not, I have removed it.

The same patch is also available as a GIT branch at:
