Then let's change the method everywhere; that avoids the exception. The idea is
to better decouple the generic code from WINDOWSNT-specific DLL issues. Revised
patches attached.

Subject: [PATCH 1/2] Wrap dll functions more simply
* decompress.c, gnutls.c, image.c, xml.c:
If WINDOWSNT, use '#define FOO fn_FOO' to wrap dll functions,
rather than the inverse when not WINDOWSNT. This isolates the
fn_* business into the WINDOWSNT-specific section of the code,
which makes it easier to maintain the generic code.
* decompress.c (DEF_ZLIB_FN, LOAD_ZLIB_FN):
* gnutls.c (DEF_GNUTLS_FN, LOAD_GNUTLS_FN):
* image.c (DEF_IMGLIB_FN, LOAD_IMGLIB_FN):
* xml.c (DEF_XML2_FN, LOAD_XML2_FN):
Remove. All uses replaced by DEF_DLL_FN.
* w32.h (DEF_DLL_FN, LOAD_DLL_FN): New macros.

From 94e65100cab8e2c9eb39c00e169ca7441864bb6b Mon Sep 17 00:00:00 2001
From: Paul Eggert <eggert@cs.ucla.edu>

Subject: [PATCH 2/2] Port memory-full checking to GnuTLS 3.3
Instead of using gnutls_global_set_mem_functions, check every call
to a GnuTLS function that might return an indication of memory
exhaustion. Suggested by Dmitry Antipov in:
http://lists.gnu.org/archive/html/emacs-devel/2014-12/msg02056.html
* gnutls.c (check_memory_full): New function.
(emacs_gnutls_handshake, emacs_gnutls_handle_error)
(gnutls_make_error, gnutls_certificate_details)
(Fgnutls_peer_status, Fgnutls_boot): Use it.
(emacs_gnutls_global_init): Avoid gnutls_global_set_mem_functions.
