Re: GDB Interrupts on Cygwin

Yes, I'm running it from a Windows console.  I had CYGWIN=tty, but
I've now removed it, and Ctrl-C still isn't working.

I tried the MinGW version of GDB.  Still no Ctrl-C.  I tried Bob's tty
'voodoo'.  Still no Ctrl-C.

I'm using GDB 6.3.50_2004-12-28-cvs (cygwin-special), I have also
compiled GDB 6.4 but it crashes immediately upon trying to debug a
program (I'm not interested in solving this problem for now).

For anyone who has gotten Ctrl-C to work on Cygwin: what version of
GDB are you using?
