Most of these warnings were between int or ssize_t and size_t. In particular, various POSIX system calls like read() and write() return ssize_t and comparing that value with the sizeof a buffer is a common source of these warnings. Another common source is using an int as the iterator in a for loop with the limit being a size_t. With the type change, some printf() specifiers needed to change also.
