> pbarea.h:52: Internal compiler error 980711. Thanks for your bug report. gcc-2.95 says pbarea.h:52: ANSI C++ forbids declaration `list' with no type pbarea.h:52: template-id `list<POLYBOOLEAN::BOCTX::TSEL>' used as a declarator pbarea.h:52: parse error before `;' [more errors] so it seems the bug has been fixed.
