With regret for raising sordid matters of implementations,... I'm having some problems getting hbc to work on i386-redhat-linux. (This has a 2.2.x kernel, and a hairy arrangement of libraries.) Trying a staticly linked rh5.2 system from chalmers, it compiles programs wonderfully, but they instantly crash, saying "Nested signal!". Something called SYS_174 is the immediate cause, but I'm baffled. If someone has got hbc to work on such a system, I'd very much appreciate it if they'd mail me. Peter
