I'm looking at this some more, and am trying to understand
what is really going on.  I can't seem to reproduce your original
issue, I think because I'm using (32-bit) mingw-w64, while the issue
with 32-bit size_t happen on (32-bit) mingw.org instead.  Correct?
But re-reading your description of the problem on bug-gnulib,
I think I get it.

BFD already uses AC_SYS_LARGEFILE, wrapped in ACX_LARGEFILE
(config/largefile.m4) due to a Solaris issue.  Actually,
the whole tree uses that -- ld, binutils, bfd, gdb, etc.,
even our toplevel gnulib/ directory's configure.ac calls it.
But then, the gnulib/import/

So maybe the best to do here is to import gnulib with 
--avoid=largefile, and let the ACX_LARGEFILE in gnulib/'s
top configure handle the enabling largefile support in sync
with all other top level dirs.  I tried that,
and confirmed that _FILE_OFFSET_BITS=64 still ends up in
gnulib's config.h.  The build then fails inside gnulib
for me on 32-bit mingw-w64, maybe there's a bug that needs
to be fixed, but I'd think this _should_ work.

See the users/palves/gnulib-largefile branch.

Thanks,
Pedro Alves
