I added #include <string.h> to the top of the file, and it seems to have
completed the build for that file.

Tommy,

Try adding:

#include <string.h>

Into packet_header_default.h and let me know how that works.

Ralph, Marcus, et al.,

I've pushed a fix just now for the 32-bit OS problem. See issue #529
for the problem/solution.

Working off-list with Ralph, we found the problem. Seems specific to
32-bit machines, though. I have to figure out what the right fix is,
but I'll get to that soon.
