sed error when compiling gnome-libs

[Dan Newcombe <Newcombe mordor clayton edu>]

I pulled Gnome-libs out of cvs this morning, and this is what I get when
compiling.  It flew along great until it came up to this monster.  Whoever
wrote this (or caused it to happend) really needs help :)  This is on an
HP-UX 10.20 machine with gnu sed version 2.05.  It also happens with sed
3.02 (just upgraded in hopes that was the problem)

Thanks for any help...so close, yet so far away :(
