Sometimes sloppiness is just sloppiness.

Never assume a deeper reason for something that can be explained by

/dev/stderr is not supported on quite a few Unix-like systems either, so
the problem is not strictly Windows-specific.  In contrast, there are
GNU programs like gawk that interpret /dev/stderr specially internally,
so this "device" works everywhere for them, even on Windows.  Guile
doesn't do that sort of device simulation.  GNU/Linux happens to have
the device for real (and probably has had so for a long time).  But I
don't think it is part of POSIX.
