[PATCH 0/2] Two minor Windows changes

[Tom Tromey]

Here are a couple of Windows-related patches that came up when I was
digging through the gdb printf code.

The first removes some dead code, then further cleans up the function
it is in.

The second is a minor change to use warning().

I tested these on Windows using the AdaCore internal test suite.  I
don't know whether these code paths are actually exercised there,
though (almost certainly not the warning path).
