* getloadavg.c: Include fcntl--.h rather than fcntl.h. Do not include unistd-safer.h. (getloadavg): Don't call fd_safer; no longer needed now that we include fcntl--.h. * getloadavg.c: Assume HAVE_UNISTD_H, i.e., include <unistd.h> unconditionally. Assume HAVE_FCNTL_H (i.e., include <fcntl.h> unconditionally, and don't include <sys/file.h>). * getloadavg.c (getloadavg) [__CYGWIN__]: Port to cygwin. [__linux__]: Allocate a big enough buffer for /proc/loadavg. [!LDAV_DONE]: Avoid unused variable warning.
