Oh, I dunno, TTYs are pretty complicated :-)

It was probably the MSVC/GCC mixing.  In fact, both problems you've
described are the same MSVC/GCC mixing problem.  This is something
I've spent a lot of time looking at recently; unfortunately, it's
a big project to fix.  It's definitely feasible, but it's more than
I can do without an interested customer.

It is not the case.  I can't promise that an upgrade will fix all your
bugs magically, but there's at least three GDB developers interested
in the Windows platform right now (it waxes and wanes somewhat).

Cool. I'll give the 7.0.1 mingw binary it a try and report any issues I find.

This is part of a bigger discussion we need to have on how we make use of EDC, if at all. Or is it just a debugger that vendors that have issues with GPL take advantage of. The one glimmer of hope I do have for it is with JNI debugging, so maybe that's where I'll focus there. Opinions welcomed.
