* msdos/sed1v2.inp (GETADDRINFO_A_LIBS, LIBLCMS2, XDBE_LIBS) (XDBE_FLAGS, HYBRID_MALLOC, LIBSYSTEMD_CFLAGS) (LIBSYSTEMD_LIBS): Edit to empty. (LIBRESOLV, DEPFLAGS, MKDEPDIR, YMF_PASS_LDFLAGS) (PRE_EDIT_LDFLAGS, POST_EDIT_LDFLAGS): Remove editing. Remove editing of lines that are no longer present in src/Makefile.in. * msdos/sed2v2.inp (NEED_MKTIME_INTERNAL) (NEED_MKTIME_WORKING): Define to 1. (HAVE_STRUCT_DIRENT_D_TYPE): Define to 1 for DJGPP >= 2.05. (HAVE_STRUCT_ATTRIBUTE_ALIGNED): Define to 1. Define PACKAGE_VERSION, not VERSION. (FLEXIBLE_ARRAY_MEMBER): Define to empty. (HAVE_DECL_*_UNLOCKED): Define to 0. (HAVE___BUILTIN_FRAME_ADDRESS): Define to 1. (PENDING_*): Don't define, as Gnulib no longer supports that. Instead, define _IOERR as it is in libc/file.h. * msdos/sed3v2.inp: Use $(CURDIR) instead of $(shell cd) to determine the current directory. (UPDATE_MANIFEST, UTILITIES): Don't edit. * msdos/sedlisp.inp (FIND_DELETE): Edit to "-delete". * msdos/sedlibmk.inp (AUTO_DEPEND): Define to yes. (HYBRID_MALLOC): Edit to empty. (am__cd): Don't edit. (../config.status): Replaces $(top_builddir)/config.status. Define OMIT_GNULIB_MODULE_foo = true for modules not built for MS-DOS. Convert GL_GENERATE_xxx_H_TRUE and GL_GENERATE_xxx_H_FALSE into values of GL_GENERATE_xxx_H. * msdos/mainmake.v2 (src): Use 'compile-one-process', and make the command line shorter to fit into 126-char limit of command.com. * config.bat: Generate src/deps/*.d files. Rename more files like djtar on plain DOS would. Don't rename src/dir.h: it is long gone. Edit lib/gnulib.mk.in using the same scripts as for lib/Makefile.in. * msdos/depfiles.bat: Create *.d files, not *.Po. * src/thread.c (Fmake_thread) [!THREADS_ENABLED]: Improve the error message. * src/thread.h [MSDOS]: Include <signal.h>. * src/sysselect.h (select) [MSDOS]: Undefine, to avoid compilation errors. * src/sysdep.c (block_interrupt_signal, restore_signal_mask): Expose to MSDOS build. * src/process.c (update_processes_for_thread_death) [!subprocess]: No-op implementation. [HAVE_SETRLIMIT]: Move inclusion of sys/resource.h and declaration of nofile_limit outside "#ifdef subprocesses", as it's needed for MSDOS. * src/msdos.c (faccessat): Declare fullname[]. * src/msdos.h (ENOTSUP): Define to be identical to ENOSYS. Include termhooks.h. * src/conf_post.h [WINDOWSNT]: Include ms-w32.h only on WINDOWSNT, not DOS_NT. * admin/admin.el (set-version): Set version on PACKAGE_VERSION.
