As I recall, HOME used to be set to a windows stye path. We certainly do
not set HOME anywhere. In fact, I see that in several places in gdbtk, we
*explicitly* convert HOME to cygwin/posix path from Windows-style path.

We also used to get NULL from getenv when you do not start it up from a
shell (i.e, you double-click the icon). Perhaps all of this has changed
(for the better) now. I don't think this was gdbtk-specific. It was a
problem looking for gdb.ini on windows.

If cygwin dll _always_ sets HOME (as you imply), then we should be able to
just get rid of all of this. Just need to verify that ~/gdb.ini is found
and loaded on windows (both with a shell and without).
