340
341 * aclocal.m4 (AC_DECL_SYS_ERRLIST): Try looking in stdio.h
342 as well since that's where glibc declares it. Go figure.
343 * signal.c (sys_sigreturn) [ALPHA]: Use sigcontext
344 instead of sigcontext_struct since glibc v5+ apparently
345 plays games with the native OS namespace.

361 Handle old and new styles of argument passing for select on Linux.
362 * ioctl.c, stream.c: Conditionalize stream code on presence of
363 sys/stream.h instead of poll because glibc implements poll but
364 not the rest of the stream interface.

383
384 * Makefile.in: Remove dependencies and rules relating to files
385 normally found in the os directory. Because of the new scheme we
386 don't know precisely where they come from. Sigh.
387 * signalent.sh: Make it work for sunos4, linux, and svr4.
388 * {sunos4,linux{,/alpha},svr4}/Makefile.in: Make rules correspond
389 to traditional make syntax. Add signalent.h to files which can
390 unconditionally be rebuilt. Prevent signalent.h from being
391 unconditionally being rebuilt since it's customized.
392 * {sunos4,linux{,/alpha},svr4}/{ioctlent,errnoent,signalent}.h:
393 Use versions built by {ioctlent,errnoent,signaltent}.sh.

405 for less, greater, and equal since subtraction on two's
406 complement numbers isn't an order relation (it isn't transitive)!
407 * linux/Makefile.in: Add rules for the signalent.h file.
408 * linux/alpha/Makefile.in: New file.

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