Yes, well these would work just fine, of course.

This is the scenario that really stinks for the FE. Currently the way
things stand on UNIX, a FE can be written nicely, and work in all
case's. However, in windows, no longer can a FE have a clean
implementation. It needs to begin guessing what output is from GDB and
what output is from the inferior.

Is there an easy and clean way to solve this problem? Maybe this problem
is easier to solve than I think it is. Any suggestions?

Honestly, I don't care if someone writes an FE that does this kind of
processing, the only reason I really care about this topic is because I
would prefer to use the TTY option in the testsuite to ensure the I/O is
separated. Doing this though, leaves target's without TTY's
semi-untested.
