I can't help you with the Windows part. On my Linux system I get
identicial output from both versions (as expected):

$ gawk-3.0.6 'BEGIN{cor="\033[1;33;40m"
>        printf "%s",cor
>        print "awk string"
> }' | od -c
0000000 033   [   1   ;   3   3   ;   4   0   m   a   w   k       s   t
0000020   r   i   n   g  \n
0000025

$ gawk-3.1.6 'BEGIN{cor="\033[1;33;40m"
>        printf "%s",cor
>        print "awk string"
> }' | od -c
0000000 033   [   1   ;   3   3   ;   4   0   m   a   w   k       s   t
0000020   r   i   n   g  \n
0000025

You might want to try recompiling from sources, either the distributed
3.1.6 or the current gawk-stable CVS from savannah.gnu.org.

Good luck,
