We find out what the (mangled) name of the constructor is. It's probably something goofy like __CONSTRUCTOR_IFL_MUMBLE__. We try defining our own C version of that, that does nothing. I'd give it a 30% chance of success. Currently we link with libz unless the user specifies --without-png --without-tiff. We could force SGIs to work by doing something horrible like (untested and not recommended): case "$opsys" in *sgi* ) with_png=no with_tiff=no ;; esac Martin
