+ * Used to declare a structure unaligned, so that the C compiler,
+ * if necessary, generates code that doesn't assume alignment.
+ * This is required because there is no guarantee that the packet
+ * data we get from libpcap/WinPcap is properly aligned.
+ *
+ * This assumes that, for all compilers that support __attribute__:
+ *
+ * 1) they support __attribute__((packed));
+ *
+ * 2) for all instruction set architectures requiring strict
+ * alignment, declaring a structure with that attribute
+ * causes the compiler to generate code that handles
+ * misaligned 2-byte, 4-byte, and 8-byte integral
+ * quantities.
+ *
+ * It does not (yet) handle compilers where you can get the compiler
+ * to generate code of that sort by some other means.
+ *
+ * This is required in order to, for example, keep the compiler from
+ * generating, for
+ *
+ * if (bp->bp_htype == 1 && bp->bp_hlen == 6 && bp->bp_op == BOOTPREQUEST) {
+ *
+ * in print-bootp.c, code that loads the first 4-byte word of a
+ * "struct bootp", masking out the bp_hops field, and comparing the result
+ * against 0x01010600.
+ *
+ * Note: this also requires that padding be put into the structure,
+ * at least for compilers where it's implemented as __attribute__((packed)).
