You shouldn't normally need to care about the endianness of your host
machine.
You do need to care about the endianness of binary format files.
Never read or write a structure directly to a file that needs to be ported.
Write the functions write16le(int x, FILE *fp) to write a 16-bit
little-endian integer to a file, and so on. Write each field individually.
That way the code works whatever happens to the C compiler's internal
structure layout.
