Greetings, David Karr!

> I'm seeing a problem with someone else's Cygwin setup, sort of similar to a

> He is using a Bash script that I wrote, and he gets a seemingly nonsensical

> main() {

Quick and dirty way to solve your issue -

$ tr -d '\r' > script.fixed < script.erring

> This was pretty perplexing,

It is actually pretty clear, though.

$ od -t x1a < script.erring

See the output.
