 gdb remains a useful tool for debugging executables on Windows, but
 getting it setup can be tricky, since modern gdb requires Python, which
 means you will end up installing MSYS Python alongside native Python.
 Unfortunately, MSYS Python doesn't work with the test suite, so one is in
 the delicate situation where you want your path to have MSYS Python if
 you're running gdb, but Windows Python if you're running the test suite.
 While one can work around this with modest annoyance (the easiest thing
 I've found is to just uninstall gdb/python when I'm not using it), it
 would be better if we removed this friction in some way.
