(AC_INIT): Use src/diff.c, not diff.h, as the source files got removed.
(AM_CONFIG_HEADER): Switch from AC_CONFIG_HEADER. (AC_ARG_PROGRAM, AC_MINIX): Remove. (AC_PREREQ, AM_INIT_AUTOMAKE, ALL_LINGUAS, AC_PROG_AWK, AM_PROG_CC_STDC, AC_PROG_RANLIB, AC_C_INLINE, AC_C_VARARRAYS, DEFAULT_DIFF_PROGRAM, DEFAULT_EDITOR_PROGRAM, AC_STRUCT_ST_MTIM_NSEC): Add. (PR_PROGRAM): AC_DEFINE. (AC_SYS_LARGEFILE): Use instead of our homebrew version. (_GNU_SOURCE): Define if not defined. (AC_CHECK_HEADERS): Add stdbool.h, unistd.h. (AC_CHECK_TYPES): Add ptrdiff_t, uintmax_t. (AM_GNU_GETTEXT, XGETTEXT): Add. (WITH_MVFS_STAT_BUG, WITH_NFS_STAT_BUG): Remove. (HAVE_MEMCHR): Remove. (AC_CHECK_FUNCS): Add diraccess. (AC_REPLACE_FUNCS): Add memchr, waitpid. (jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_GNU_STRFTIME, jm_FUNC_MALLOC, jm_FUNC_REALLOC, jm_PREREQ_ERROR, jm_PREREQ_QUOTEARG, jm_PREREQ_REGEX, jm_PREREQ_TEMPNAME, jm_AC_PREREQ_XSTRTOUMAX, AC_FUNC_FNMATCH): Add. (fnmatch.h, regex.h): Do not create these files unless we're using our own fnmatch and regex. (AC_OUTPUT): Add doc/Makefile, intl/Makefile, lib/Makefile, lib/posix/Makefile, m4/Makefile, po/Makefile.in, src/Makefile.
