w32 port: SVG Path Commands' has no Up field (perhaps incorrect sectioning?).

[Keith David Bershatsky]

When building master branch from today 
(0797b39185e66983c7286e89f93dd4f6c83b6ea7) on Windows 32 (minGW and ezwinports 
downloaded a few years ago) with the following build options:

CFLAGS='-O0 -g3' ./configure \
--prefix=/c/docume~1/admini~1/desktop/trunk \
--enable-checking='yes,glyphs' \
--enable-check-lisp-object-type \
--without-compress-install \
--without-makeinfo \
--with-gnutls=no \
--with-mailutils \
--without-makeinfo

... the build stops with the following output:
