I've been trying to get rsvg working and here's what I found:
First, building xml.o fails:

This code only runs when mbstate_t check fails. Let's look at why it fails:

Since stat.h is in mingwrt, I decided to check whether older versions
work. And sure, mingwrt-3.21.1 works fine.
Then, there's a similar situation with glib:

Installing w32api-3.17-2-mingw32-dev.tar.lzma helped.

So wchar.h now includes sys/stat.h? What MinGW runtime are you using
and where did you download it?
Does it help to add the following to nt/inc/sys/stat.h?
#ifndef _SYS_STAT_H
#define _SYS_STAT_H
#endif
The best solution in the long run is to stop redefining struct stat
and friends, and instead call it something else (since we don't use
the MS implementation of 'stat' and 'fstat' anyway). Patches to that
effect are welcome.

Libxml and glib are dependencies for it.

This happens with mingwrt-3.22.2-mingw32-dev.tar.xz, you can download it
manually from MinGW sourceforge, it's also the default version you would
get from mingw-get. Generally, building with it works, only with libxml
fails.

Ok, gonna try later.

Makes sense, what about MemoryBarrier?

Define away the one glib insist of giving us? Like this:
#if __W32API_MAJOR_VERSION + (__W32API_MINOR_VERSION >= 18) >= 4
# define MemoryBarrier glib_MemoryBarrier
#endif
#include <librsvg/rsvg.h>
#undef MemoryBarrier
Does that work?

Never mind, I think I fixed this, on both emacs-25 and master. Please
see if there's any fallout, or else close the bug report.
Thanks.
