But this doesn't create any pipes to communicate with GDB.  Instead,
this communicates via the default stdin/stdout connected to the
console, and GDB should recognize it as such.  So all the problems you
describe should not happen, and indeed don't happen for me when I
invoke GDB from cmd.exe.

Do you perhaps have a ~/.inputrc file, or some other local
customization, which might affect how Readline works?  because what
you describe surely sounds like broken Readline.
