Maybe a little/big endian issue? You cannot use constructions like this:

char *buf[SIZE];
int x;
/* read in the buffer here */
memcpy((void *)&x, buf+X_OFFSET, sizeof(int));   /* WRONG! */

You should use the htons() and htonl() functions on win32 in order to
correct the little/big endian problem.
