[LAU] polarbear (zplane editor) on recent gcc's?

Has anyone compiled Maarten de Boer's "polarbear" on recent compilers? I just downloaded polarbear-0.5.3 from http://www.resorama.com/maarten/files/polarbear-0.5.3.tgz. While compiling it complains about some things i beleive are related to the version of the compiler. Hacking it slightly, the app seems to run ok, adressing jack correctly. Ive got some questions about the edit-menu - select, cut, copy... - but am unsure whether ive got a fully functional copy up, and dont know how they are meant to behave. Maarten de Boer, maybe you are out there? Polarbear functions similarly to a sorely missed app from the old NeXT's, an interactive z-plane editor (ive forgotten the name, but i beleive it was setup by someone at ccrma) where coefficients were made available in the clipboard after manipulating the filter in the gui. Maybe there are other similar tools around? Thanks, -anders
