Re: COBOL support in GDB

Hi.

That is not a very welcoming message to read as the second message Bob 
ever received in this community. If you are just genuinely surprised 
that someone is working with COBOL (or any other technology for that 
matter), I encourage you to be a little more careful with your wording, 
like "wow, I didn't know it was still this important" or "that is very 
surprising, but good luck".

The way your email is worded, it sounds rather dismissive of his efforts 
to add support, which makes the GDB community seem unapproachable.
