Details:

When I run make-4.1 with the attached makefile I get the following error

bug7.mk:5: *** missing separator.  Stop.

This behavior looks inconsistent, because expanding variable D should give two
empty lines, which should then be ignored by make.
Such problem could be avoided by inserting a continue statement at
read.c:1509, as shown below.

      /* If the line doesn't begin with a tab, test to see if it introduces
         another define, or ends one.  Stop if we find an 'endef' */
      if (line[0] != cmd_prefix)
        {
          p = next_token (line);
          len = strlen (p);
          if (!len) continue; /* skip empty lines */
