You are using the quote characters inside quoted strings; DOS/Windows
shells do not cope well with these.  I suggest to try these commands
instead:

  gawk 'BEGIN {printf(\"================first\")}'> out.txt
  gawk 'BEGIN {printf(\"++++second+\");}'>> out.txt

That is, use single quotes instead of double quotes for the outer
quotes.  That should work in either shell.

I have no idea why the older Gawk worked.  Perhaps you use a non-DJGPP
port of that version, or maybe the DJGPP startup code that deals with
quotes has changed between the two ports.
