+ * - Making various functions return int rather than size_t.
+ * (Undoing a recent change). Since size_t is unsigned on
+ * Windows, functions like read_socket that return -1 on
+ * error cannot return a size_t.
+ *
+ * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
+ * crashes, and also frequently caused JB to jump to 100%
+ * CPU and stay there. (Because it thought it had just
+ * read ((unsigned)-1) == 4Gb of data...)
+ *
+ * - The signature of write_socket has changed, it now simply
+ * returns success=0/failure=nonzero.
+ *
+ * - Trying to get rid of a few warnings --with-debug on
+ * Windows, I've introduced a new type "jb_socket". This is
+ * used for the socket file descriptors. On Windows, this
+ * is SOCKET (a typedef for unsigned). Everywhere else, it's
+ * an int. The error value can't be -1 any more, so it's
+ * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
+ * Windows it maps to the #define INVALID_SOCKET.)
+ *
+ * - The signature of bind_port has changed.
+ *
+ * Revision 1.48 2002/03/07 03:46:53 oes
+ * Fixed compiler warnings etc
+ *
* Revision 1.47 2002/02/20 23:15:13 jongfoster
* Parsing functions now handle out-of-memory gracefully by returning
* an error code.
* file, the results are not portable.
