+ *    Revision 1.53  2007/09/09 18:20:20  fabiankeil
+ *    Turn privoxy_strlcpy() into a function and try to work with
+ *    b0rked snprintf() implementations too. Reported by icmp30.
+ *
+ *    Revision 1.52  2007/08/19 12:32:34  fabiankeil
+ *    Fix a conversion warning.

+ *    Revision 1.51  2007/06/17 16:12:22  fabiankeil
+ *    #ifdef _WIN32 the last commit. According to David Shaw,
+ *    one of the gnupg developers, the changes are mingw32-specific.
+ *
  *    Revision 1.50  2007/06/10 14:59:59  fabiankeil
  *    Change replacement timegm() to better match our style, plug a small
  *    but guaranteed memory leak and fix "time zone breathing" on mingw32.
