For example:
$ printf "a\nb\n\n" \
   | /usr/bin/nawk 'BEGIN{RS="\n\n"; ORS="=\n"} {print}'
a=
b=
=
$ printf "a\nb\n\n" \
   | /usr/bin/awk 'BEGIN{RS="\n\n"; ORS="=\n"} {print}'
a=
b=
=
$ printf "a\nb\n\n" \
   | /usr/xpg4/bin/awk 'BEGIN{RS="\n\n"; ORS="=\n"} {print}'
a=
b=
=

But the gawk is right here:
$ printf "a\nb\n\n" \
   | /usr/bin/gawk 'BEGIN{RS="\n\n"; ORS="=\n"} {print}'
a
b=
