/*
 * Miscellaneous definitions
 *
 * Even within a particular hardware and OS type, not all systems
 * are configured identically.  Some systems may need additinal
 * definitions, some of which are included below.   Note that for
 * some system types, these are automatically defined.
 *
 * define ARDP_MY_WINDOW_SZ if your system has some sort of internal limit
 *   on the number of UDP packets that can be queued.  SOLARIS has a limit of
 *   9 or less (6 seems to work for Pandora Systems), which inspired 
 *   this change.  If defined, the client will explicity request that 
 *   the server honor this window size.  This reduces retries and wasted
 *   messages. 
 * define NEED_MODE_T if mode_t is not typedefed on your system
 * define DD_SEEKLEN if your system doesn't support dd_bbase and dd_bsize
 * define DIRECT if direct is the name of your dirent structure
 *      This generally goes along with using sys/dir.h.
 * define USE_SYS_DIR_H if your system doesn't include sys/dirent.h, and
 *      sys/dir.h should be used instead.
 * define CLOSEDIR_RET_TYPE_VOID if your closedir returns void
 * Define GETDENTS if your system supports getdents instead of getdirentries
 * Define OPEN_MODE_ARG_IS_INT if your system has the optional third argument
 *   to open() as an int.  Don't #define it if the optional third argument to
 *   open() is a mode_t.  You will need to #undef this if you're using the
 *   sysV interface to SunOS.
 * Define SIGCONTEXT_LACKS_SC_PC if your system's sigcontext structure lacks
 *   an sc_pc member.  This appears to be the case on HPUX version 8.07 on the
 *   HP 9000 series 700 workstations.  I don't know if it's the case anywhere
 *   else, and I suspect it's a bug in the release that will be fixed later.
 * Define PROTOTYPE_FOR_OPEN_HAS_EMPTY_ARGLIST if your system prototypes the
 *   open() function with an empty argument list.  This is necessary because
 *   gcc requires the prototype to match the function invocation.
 * Define PROTOTYPE_FOR_SELECT_USES_INT_POINTER if your system prototypes the
 *   select() function with 'int *' for the second, third, and fourth arguments
 *   instead of 'fd_set *'.  
 * Define BSD_UNION_WAIT if your system doesn't support the new POSIX wait()
 *   interface and does support the old BSD wait() interface and 'union wait'
 *   member. 
 * Define INCLUDE_FILES_LACK_FDOPEN_PROTOTYPE if your system's <stdio.h> lacks
 *   an fdopen() prototype.
 * Define INCLUDE_FILES_LACK_POPEN_PROTOTYPE if your system's <stdio.h> lacks
 *   an popen() prototype.
 * Define INCLUDE_FILES_LACK_TEMPNAM_PROTOTYPE if your system's <stdio.h> lacks
 *   a prototype for tempnam().
