Two years without updates? Now that's severely broken...

Actually you shouldn't post the file as /attachment/ here...

And it doesn't say where the other ones are?

It's your software. You installed it there. So you should know what's 
in there. Anyway: simply removing an element from the path doesn't 
"break" anything - you just have to type the full name. You don't have 
to have any Cygwin knowledge for that - basic Windows and Unix 
knowledge is enough for that.

Is that a serious question? Why do you install two compilers?! You 
/must/ have already noticed that one of them is not what you used to 
get when you type gcc. If you don't need them uninstall them both.
