Thu Jul 18 04:33:21 1996 Roland McGrath <roland@baalperazim.frob.com>cvs/libc-960718
* sysdeps/mach/hurd/errnos.awk: Move EWOULDBLOCK check before errno==0
check. mib's clueless hacking broke it.
Thu Jul 18 04:27:21 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* Makerules ($(libdir)/libc.so): Add missing / after $(cryptobjdir).
Wed Jul 17 10:54:20 1996 David Mosberger-Tang <davidm@azstarnet.com>
* sysdeps/unix/sysv/linux/alpha/start.S: Move to ...
* sysdeps/alpha/elf/start.S: here.
* misc/sys/ustat.h: New file.
* misc/ustat.h: Ditto.
* sysdeps/generic/ustatbits.h: Ditto.
* libc-orig/sysdeps/stub/ustat.c: Ditto.
* sysdeps/unix/sysv/linux/ustatbits.h: Ditto.
* misc/Makefile (headers): Mention ustat.h, sys/ustat.h, and
ustatbits.h.
(routines): Mention ustat.
* sysdeps/unix/sysv/linux/syscalls.list: Mention klogctl in
alphabetically correct place. Mention ustat.
* sysdeps/unix/alpha/sysdep.S: Make errno a bss symbol, not a
common symbol (makes errno accessible from gdb).
* login/pututline_r.c (pututline_r): Test ut_id in repositioning
test, not ut_type.
* login/logwtmp.c (logwtmp): Reimplemented. Must ensure that a
record always gets appended at end of file (wtmp is a log file,
after all). Set ut_type to DEAD_PROCESS if name is empty.
* login/getutid_r.c (getutid_r): Handle search for UT_TYPE in
separate loop from search for UT_ID. Fix code so it is in
sync with Unix man page.
* login/getutline_r.c (getutline_r): Stop searching only if
ut_line matches and type is either USER_PROCESS or LOGIN_PROCESS.
Tue Jul 16 15:06:18 1996 David Mosberger-Tang <davidm@azstarnet.com>
* sysdeps/unix/sysv/linux/netinet/in.h: Base on <linux/in.h> to
avoid duplicate declarations.
Sun Jul 14 19:08:55 1996 David Mosberger-Tang <davidm@azstarnet.com>
* manual/maint.texi (Supported Configurations): Add alpha-gnu-linux
and alpha-gnu-linuxecoff targets.
Fri Jul 12 16:58:44 1996 David Mosberger-Tang <davidm@azstarnet.com>
* sysdeps/unix/sysv/linux/netinet/in.h: Declare bindresvport().
Sat Jun 22 23:30:07 1996 David Mosberger-Tang <davidm@azstarnet.com>
* resolv/res_send.c (res_send): Declare FROMLEN as size_t instead
of int.
* resolv/res_comp.c (res_hnok): Use empty statement in place
of NULL (which generates a "useless expression" warning in
gcc).
