Reorder ChangeLog entries to match the order in which the changes went in at the central repository. doc: Mention new glibc headers and functions. ftell: don't include <unistd.h> ftell: do not assume wraparound signed arithmetic Attribution for last commit. close: No longer depend on module 'fclose'. fsusage: Enable large volume support on AIX >= 5.2. fsusage: Restore previous behaviour on AIX, Cygwin, Interix. fsusage: Support large volumes on glibc/Hurd, HP-UX, Solaris, MacOS X. * README: Modernize discussion of signed integers. select tests, pselect tests: Refactor. sys_select tests: Check the signature of FD_*. largefile: new module, replacing large-inode fsusage: port to MacOS X 10.7 with 4 TiB file systems large-inode: New module extensions: Enable extensions on MacOS X 10.5 and later. file-has-acl: use acl_extended_file_nofollow if available Declare system functions in a way that works with C++. maint.mk: prohibit inclusion of "verify.h" without use timer-time: A new module to check for timer_settime() pthread_sigmask: assume POSIX threads if --avoid=threadlib strstr: Update cross-compilation guess. getopt-gnu: suppress core dumps from detection code pthread_sigmask: ensure usleep is declared doc: Document NonStop portability issues. ffsl, ffsll: Avoid unportable behaviour. ffs: More tests. ffsl, ffsll: new modules ffs: fix m4 prerequisite ffs: avoid undefined behavior pthread_sigmask: Rely on module 'threadlib'. regex: Depend on module 'strcase'. warn-on-use: fix typo in file name strings: Document module. Rename module '_Noreturn' to 'snippet/_Noreturn'. Mention the changes. Rename module 'warn-on-use' to 'snippet/warn-on-use'. Rename module 'unused-parameter' to 'snippet/unused-parameter'. Rename module 'link-warning' to 'snippet/link-warning'. Rename module 'c++defs' to 'snippet/c++defs'. Rename module 'arg-nonnull' to 'snippet/arg-nonnull'. Improve ChangeLog to summarize _Noreturn better. modules/_Exit-tests: test _Noreturn too stdnoreturn, stdnoreturn-tests: remove modules _Noreturn: Ignore __STDC_VERSION__; observe _MSC_VER. _Noreturn-tests: remove module * top/maint.mk: Adjust to new noreturn support. xalloc: use stdnoreturn.h xstrtol: use stdnoreturn.h xmemdup0: use stdnoreturn.h sigpipe-die: use stdnoreturn.h openat: use stdnoreturn.h * lib/openat-die.c (openat_save_fail): Modernize comment. * lib/xalloc-die.c (xalloc_die): Modernize comment. * lib/glthread/thread.h: Modernize comment. obstack: use _Noreturn c-stack: use _Noreturn exclude_tests: use _Noreturn argmatch-tests: use _Noreturn stdlib: use _Noreturn stdnoreturn-tests: new module stdnoreturn: new module _Noreturn-tests: new module _Noreturn: new module * m4/gnulib-common.m4 (gl_COMMON_BODY): Add _Noreturn.
