	(windows_get_exec_module_filename): Add pointer casts for C++.

gdb/gdbserver/ChangeLog:

2016-06-02  Jon Turney  <jon.turney@dronecode.org.uk>

Seems like you also created a "2.24.51.20140326" tag at
the same time?

Yes.

I guess turning on push.followTags globally wasn't such a good idea.

It seems I cannot remove this tag, please do so.

do this?

Of course, done! For the record:

    % git tag -d 2.24.51.20140326
    Deleted tag '2.24.51.20140326' (was de7067d)
