Thomas, the libgcc problem might be a gcc installation problem. Just specifying -lgcc should be enough to get libgcc linked in. Furthermore, depending on how the linking is done (gcc -shared?), it shouldn't be necessary *at all* to provide -lgcc. This isn't so much a HPUX question but more a gcc question: if you link with gcc, it *ought* to work (if you link with ld(1), you are on your own).
