-/* Compile-time symbols that this file uses:
-   HAVE_PSTAT_GETDYNAMIC        Define this if your system has the
-                                pstat_getdynamic function.  I think it
-                                is unique to HPUX9.  The best way to get the
-                                definition is through the AC_FUNC_GETLOADAVG
-                                macro that comes with autoconf 2.13 or newer.
-                                If that isn't an option, then just put
-                                AC_CHECK_FUNCS(pstat_getdynamic) in your
-                                configure.in file.
-   FIXUP_KERNEL_SYMBOL_ADDR()   Adjust address in returned struct nlist.
-   KERNEL_FILE                  Name of the kernel file to nlist.
-   LDAV_CVT()                   Scale the load average from the kernel.
-                                Returns a double.
-   LDAV_SYMBOL                  Name of kernel symbol giving load average.
-   LOAD_AVE_TYPE                Type of the load average array in the kernel.
-                                Must be defined unless one of
-                                apollo, DGUX, NeXT, or UMAX is defined;
-                                or we have libkstat;
-                                otherwise, no load average is available.
-   HAVE_NLIST_H                 nlist.h is available.  NLIST_STRUCT defaults
-                                to this.
-   NLIST_STRUCT                 Include nlist.h, not a.out.h, and
-                                the nlist n_name element is a pointer,
-                                not an array.
-   HAVE_STRUCT_NLIST_N_UN_N_NAME `n_un.n_name' is member of `struct nlist'.
-   LINUX_LDAV_FILE              [__linux__, __CYGWIN__]: File containing
-                                load averages.

-   __NetBSD__                   NetBSD: assumes /kern file system mounted.
-   In addition, to avoid nesting many #ifdefs, we internally set
-   LDAV_DONE to indicate that the load average has been computed.
