Depend on $(..)Makeconfig. * GMP code updated from gmp-2.0 release. * stdlib/Makefile (mpn-routines): Removed add_1, added inlines. * sysdeps/generic/add_1.c: File removed. * stdlib/strtod.c: mp_limb is now mp_limb_t. * stdlib/fpioconst.c, stdlib/fpioconst.h: Likewise. * stdio-common/_itoa.c: Likewise. * stdio-common/printf_fp.c: Likewise. Don't include ansidecl.h. * sysdeps/mach/hurd/getcwd.c: Use io_identity instead of io_stat. * shlib-versions: New file. * Makerules (soversions.mk): New target, include file generated from shlib-versions. Moved shared library rules before installation rules.

Sun May 5 03:10:44 1996 Ulrich Drepper * misc/efgcvt_r.c (ecvt_r): Work aroung gcc bug. gcc does not know about weak aliases now and optimizes necessary `if' statement away. * posix/unistd.h: Add swapoff prototype. * sysdeps/generic/confname.h: Add even more POSIX.4 symbols. * sysdeps/posix/fpathconf.c (__fpathconf): Get information for _PC_PATH_MAX from fstatfs function if available. * sysdeps/posix/sysconf.c: Add code to handle _SC_AIO_LISTIO_MAX, _SC_AIO_MAX, _SC_AIO_PRIO_DELTA_MAX, _SC_DELAYTIMER_MAX, _SC_MQ_OPEN_MAX, _SC_MQ_PRIO_MAX, _SC_RTSIG_MAX, _SC_SEM_NSEMS_MAX, _SC_SEM_VALUE_MAX, _SC_SIGQUEUE_MAX, and _SC_TIMER_MAX. * sysdeps/unix/sysv/sysv4/sysconf.c: Ditto. * sysdeps/stub/swapoff.c: New file. Stub version for swapoff function. * sysdeps/unix/syscalls.list: Add swapoff. * sysdeps/unix/sysv/linux/Dist: Add sys/acct.h. * sysdeps/unix/sysv/linux/Makefile [$(subdir) == misc] (sysdep_routines): Add mount, umount, llseek, setfsgid, setfsuid, sysinfo, and uselib. (headers): Add sys/sysinfo.h. * sysdeps/unix/sysv/linux/gethostid.c: Prevent warning. * sysdeps/unix/sysv/linux/i386/Makefile [$(subdir) == misc] (sysdep_routines): Add ioperm, iopl, and vm86. (headers): Add sys/perm.h and sys/vm86.h. * sysdeps/unix/sysv/linux/i386/sys/perm.h: New file. Contains prototypes for iopl and ioperm. * sysdeps/unix/sysv/linux/i386/sys/vm86.h: New file. Contains prototype for vm86. * sysdeps/unix/sysv/linux/i386/syscalls.list: New file. Add vm86 system call. * sysdeps/unix/sysv/linux/sys/acct.h: New file. Contains prototypes for acct function. * sysdeps/unix/sysv/linux/sys/socket.h: Provide real header file with prototypes. * sysdeps/unix/sysv/linux/sys/sysinfo.h: New file. Contains prototype for sysinfo function. * sysdeps/unix/sysv/linux/syscalls.list: Add flock, ioperm, iopl, llseek, setfsgid, setfsuid, sysinfo, and uselib. * sysdeps/unix/sysv/linux/sysconf.c: Instead of duplicating posix/sysconf.c now only handle cases different to that implementation. Tue May 7 15:08:19 1996 Miles Bader * stdio/linewrap.c (__line_wrap_output): Renamed from lwoutput (all references changed). Now exported. * stdio/linewrap.c (struct data): Type deleted (moved to linewrap.h). (wrap_stream, unwrap_stream, lwclose, lwfileno, lwoutput, line_wrap_stream, line_unwrap_stream): Use struct line_wrap_data instead of struct data. (lwoutput, line_wrap_stream, line_unwrap_stream): Rename various occurences of `wrap' and `wrapmargin' to `wmargin'. (line_wrapped, line_wrap_lmargin, line_wrap_set_lmargin, line_wrap_rmargin, line_wrap_set_rmargin, line_wrap_wmargin, line_wrap_set_wmargin, line_wrap_point): New functions. * stdio/linewrap.h: New file. * stdio/Makefile (headers): Add linewrap.h.
