I think it boils down to the question if you can use ELF relocations to create a relocatable (but not necessarily position-independent) object that ld can link with the SBCL run-time system to produce an executable. This executable would truly be stand-alone because no separate core file is required anymore. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
