"It seems like the issue is awk specific under Cygwin. I tried a few
different things and it seems that awk is silently treating replacing
\r\n with \n in the input data."

On Linux (good, we have cr and nl)
$ echo $'line1\r\nline2'|awk 1|od -a
0000000 l i n e 1 cr nl l i n e 2 nl
0000015
On Cygwin or MSYS (bad, we have only a cr)
$ echo $'line1\r\nline2'|awk 1|od -a
0000000 l i n e 1 nl l i n e 2 nl
0000014
