* 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().
