--- Comment #6 from Yaakov (Cygwin Ports) <yselkowitz at users dot sourceforge.net> --- Not only that, but even with --enable-install-libiberty, it's not being installed in CVS HEAD. Don't you need to remove the resetting of target_header_dir in libiberty/configure.ac:408 (and hence libiberty/configure:5510)?
