Update.
1999-07-30 Andreas Schwab <schwab@suse.de> * sysdeps/unix/sysv/linux/getsysstats.c (GET_NPROCS_PARSER): New definition. (__get_nprocs): Use it. (__get_nprocs_conf): Define as separate function if GET_NPROCS_CONF_PARSER is defined. * sysdeps/unix/sysv/linux/alpha/getsysstats.c: New file. * include/sys/sysinfo.h: New file. * sysdeps/generic/sys/sysinfo.h: Remove declaration of internal interface. * sysdeps/unix/sysv/linux/sys/sysinfo.h: Likewise. 1999-07-30 H.J. Lu <hjl@gnu.org> * libio/iofflush.c (fflush_unlocked): Weak aliase if _IO_MTSAFE_IO is not defined. * libio/clearerr.c (clearerr_unlocked): Likewise. * libio/feof.c (feof_unlocked): Likewise. * libio/ferror.c (ferror_unlocked): Likewise. * libio/fputc.c (fputc_unlocked): Likewise. * libio/getc.c (getc_unlocked, fgetc_unlocked): Likewise. * libio/getchar.c (getchar_unlocked): Likewise. * libio/putc.c (putc_unlocked): Likewise. * libio/putchar.c (putchar_unlocked): Likewise. 1999-07-30 Thorsten Kukuk <kukuk@suse.de> * sunrpc/Versions: Add svc_getreq_common, svc_getreq_poll, svc_max_pollfd and svc_pollfd to GLIBC_2.2 * sunrpc/rpc/svc.h: Use rpc*_t types, add new prototypes for svc_run/poll interface. * sunrpc/rpc/types.h: Add rpc*_t typedefs. * sunrpc/rpc_common.c: Add svc_pollfd and svc_max_pollfd as global variable. * sunrpc/svc.c: Add svc_getreq_poll and svc_getreq_common, rewrite other svc_getreq* functions to use svc_getreq_common. * sunrpc/svc_run.c: Use poll(). 1999-07-30 Andreas Schwab <schwab@suse.de> * Makerules: Put sysd-versions and Versions.all on postclean-generated instead of common-generated. 1999-07-29 Andreas Jaeger <aj@arthur.rhein-neckar.de> * manual/time.texi (Basic CPU Time): Note that clock_t can wrap around and CLOCKS_PER_SEC is 1e6.
