+ * Revisions :
+ * $Log: amiga.c,v $
+ * Revision 1.9 2002/03/26 22:29:54 swa
+ * we have a new homepage!
+ *
+ * Revision 1.8 2002/03/25 19:32:15 joergs
+ * Name in version string changed from junkbuster to Privoxy.
+ *
+ * Revision 1.7 2002/03/24 13:25:43 swa
+ * name change related issues
+ *
+ * Revision 1.6 2002/03/09 20:03:52 jongfoster
+ * - 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 1.5 2002/03/03 09:18:03 joergs
+ * Made jumbjuster work on AmigaOS again.
+ *
+ * Revision 1.4 2001/10/07 15:35:13 oes
+ * Replaced 6 boolean members of csp with one bitmap (csp->flags)
+ *
+ * Revision 1.3 2001/09/12 22:54:51 joergs
+ * Stacksize of main thread increased.
+ *
+ * Revision 1.2 2001/05/23 00:13:58 joergs
+ * AmigaOS support fixed.
+ *
+ * Revision 1.1.1.1 2001/05/15 13:58:46 oes
+ * Initial import of version 2.9.3 source tree
