v6 -> v7: - This version compiles and works with both GCC (tested 6.1.1) and with Clang (tested 3.8.0).
- Uses -m16 mode on both compilers to generate i8086 code. - The signrom.py script has been modified so it can (optionally) generate the size field in the header. - Tested with both a small (libguestfs) and large (Fedora 23) initrd. Rich.
