Absolutely.
Before [1], this structure was defined by including Cygwin's
<sys/procfs.h> (so this code didn't work in cross-environments).
I can't find a model of adding note structure definitions (the other
grok_note functions seem to rely on OS definitions), so I'm not sure
what kind of change you are asking me to make in this patch.
