On Cygw32, it seems that cache_system_info (in src/w32fns.c) is never
called.  So, os_subtype is not initialized and selection-coding-system
is not set to unicode in my environment.

$ emacs -Q
C-h v selection-coding-system

selection-coding-system is a variable defined in `select.el'.
Its value is cp932-dos

It should be called early on during startup, so perhaps a cygw32-only
call to it near the beginning of 'main' is all that's needed.

(Does the cygw32 build use w32_num_mouse_buttons? if not, that part of
cache_system_info should be #ifdef'ed away on Cygwin.)

Yes, Cygw32 build also uses w32_num_mouse_buttons in w32_wnd_proc.

I don't have a cygw32 system, but I have a cygw64, and there:

----
selection-coding-system is a variable defined in ‘select.el’.

Its value is ‘utf-16le-dos’
----

Is this still an issue on cygw32 systems, or has it gone away in the
eight years since this was reported?

It seems that the problem has been already resolved though I don't
know when.

Thanks for checking; I'm closing this bug report, then.
