/* Compile-time symbols that this file uses:
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.
- NLIST_NAME_UNION struct nlist has an n_un member, not n_name.
+ HAVE_STRUCT_NLIST_N_UN_N_NAME `n_un.n_name' is member of `struct nlist'.
LINUX_LDAV_FILE [__linux__]: File containing load averages.
+ HAVE_LOCALE_H locale.h is available.
+ HAVE_SETLOCALE The `setlocale' function is available.
Specific system predefines this file uses, aside from setting
default values if not emacs:
