unistd et al.: Don't assume <unistd.h> exists. * m4/chdir-long.m4 (gl_FUNC_CHDIR_LONG): Don't include <unistd.h> if it does not exist. * m4/environ.m4 (gl_ENVIRON): Don't include <unistd.h> if it does not exist. But include <stdlib.h>. * m4/fcntl-o.m4 (gl_FCNTL_O_FLAGS): If <unistd.h> does not exist, include <io.h> and <stdlib.h> instead. Don't test symbolink links if symlink() does not exist. * m4/fflush.m4 (gl_FUNC_FFLUSH_STDIN): If <unistd.h> does not exist, include <io.h> instead. * m4/free.m4 (gl_FUNC_FREE): Assume free(NULL) works on native Windows. * m4/getcwd.m4 (gl_FUNC_GETCWD_NULL): If <unistd.h> does not exist, include <direct.h> instead. * m4/getcwd-abort-bug.m4 (gl_FUNC_GETCWD_ABORT_BUG): Likewise. * m4/getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX): Likewise. * m4/lseek.m4 (gl_FUNC_LSEEK): If <unistd.h> does not exist, include <io.h> instead. * m4/rename.m4 (gl_FUNC_RENAME): Assume rename() manages hard links correctly if the system does not have hard links. * m4/rmdir.m4 (gl_FUNC_RMDIR): If <unistd.h> does not exist, include <direct.h> instead. * m4/unistd_h.m4 (gl_UNISTD_H): If <unistd.h> does not exist, bypass it when looking for function declarations. * m4/unlink.m4 (gl_FUNC_UNLINK): If <unistd.h> does not exist, include <direct.h> and <io.h> instead. * doc/posix-headers/unistd.texi: More details about MSVC problem.
