24 Sun Oct 27 22:28:00 1996 J. Richard Sladkey <jrs@world.std.com>
26 * util.c (umovestr) [LINUX]: Handle Linux like SunOS4
27 instead of SVR4. That is, read a few bytes at a time
28 to avoid overrunning the end of the stack.
30 Fri May 31 01:48:49 1996 J. Richard Sladkey <jrs@world.std.com>
32 * version.c: Version 3.1 is released.
34 Thu May 23 01:04:43 1996 J. Richard Sladkey <jrs@world.std.com>
36 * aclocal.m4 (AC_DECL_SYS_ERRLIST): Try looking in stdio.h
37 as well since that's where glibc declares it. Go figure.
38 * signal.c (sys_sigreturn) [ALPHA]: Use sigcontext
39 instead of sigcontext_struct since glibc v5+ apparently
40 plays games with the native OS namespace.
41 From David Mosberger-Tang <davidm@AZStarNet.com>.
43 Mon May 20 23:17:14 1996 J. Richard Sladkey <jrs@world.std.com>
45 * version.c: Version 3.0.14 is released.
47 * aclocal.m4 (AC_STRUCT_MSG_CONTROL): New macro.

49 * net.c (printmsghdr): Handle BSD 4.3 and 4.4 msghdr members
51 Reported by Henrik Storner <storner@osiris.ping.dk>.
53 * configure.in: (AC_CHECK_{HEADERS,FUNCS}): Add checks for
54 sys/filio.h and sys/stream.h and remove check for poll.
55 * desc.c (decode_select, sys_select, sys_oldselect) [LINUX]:
56 Handle old and new styles of argument passing for select on Linux.
57 * ioctl.c, stream.c: Conditionalize stream code on presence of
58 sys/stream.h instead of poll because glibc implements poll but
59 not the rest of the stream interface.
60 * signal.c [LINUX]: Standardize on the name sigcontext_struct.
61 (sys_sigprocmask) [ALPHA]: Handle OSF flavor which is more like
63 * term.c (term_ioctl): Use _VMIN, if present, for TC{G,S}ETA*.
64 * util.c (umoven, umovestr): Move data in long-sized chunks
65 at a time, instead of hard coding it to be 4.
66 From David Mosberger-Tang <davidm@AZStarNet.com>.

75 locally if the header is present.
77 * syscall.c (nerrnos{0,2}): Correct size computation.
79 * Makefile.in: Remove dependencies and rules relating to files
80 normally found in the os directory. Because of the new scheme we
81 don't know precisely where they come from. Sigh.
82 * signalent.sh: Make it work for sunos4, linux, and svr4.
83 * {sunos4,linux{,/alpha},svr4}/Makefile.in: Make rules correspond
84 to traditional make syntax. Add signalent.h to files which can
85 unconditionally be rebuilt. Prevent signalent.h from being
86 unconditionally being rebuilt since it's customized.
87 * {sunos4,linux{,/alpha},svr4}/{ioctlent,errnoent,signalent}.h:
88 Use versions built by {ioctlent,errnoent,signaltent}.sh.
89 * sunos4/ioctlent.sh: Work around sprintf troubles with SunOS

100 for less, greater, and equal since subtraction on two's
101 complement numbers isn't an order relation (it isn't transitive)!

137 From Thomas Bogendoerfer <tsbogend@bigbug.franken.de>.
139 Fri May 17 00:50:06 1996 J. Richard Sladkey <jrs@world.std.com>
141 * version.c: Version 3.0.10 is released.
143 * Makfile.in: Add os/arch to includes so that a given arch
144 (like alpha) can override the native arch (like i386).
145 * configure.in: Check for sendmsg.
147 * net.c: Make sendmsg and recvmsg dependent on an autoconf
148 test. Reported by Michael E Chastain <mec@duracef.shout.net>.

156 major and minor results are suitable for passing to printf.
157 * signal.c, syscall.c: Support the alpha.
158 * process.c: Add alpha user offsets.
159 * most files: Use %l? for printf arguments since
160 most are now longs for the alpha.
161 * linux/alpha/{errnoent.h,ioctlent.{h,sh},syscallent.h}:
163 From Thomas Bogendoerfer <tsbogend@bigbug.franken.de>.

593 syscall which doesn't work on Irix5.2.
594 * svr4/dummy.h: Add new unfinished SGI syscalls
595 (e.g. sys_sysmp, sys_sginap, etc.). Handle some SGI syscalls like
