I don't know the answer, but I'm guessing that when you cross-compile from an i386 to an x86-64 that the C files are generated with the expectation that a 64-bit C compiler will compile them (whether cross compiled from i386 or native compiled on the target machine). > Also, why don't we just teach LIAR to open-code > SET-STRING-MAXIMUM-LENGTH! ? I can't imagine it is worth the effort and pain. You don't want to build too much knowledge of object representation into the compiler unless you really need it. Open coding would save the function call and some argument shuffling, but you'd still be doing the other work. -- ~jrm _______________________________________________ MIT-Scheme-devel mailing list MIT-Scheme-devel@gnu.org http://lists.gnu.org/mailman/listinfo/mit-scheme-devel
