+ 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.
+ * decompress.c (inflateInit2): Remove; no longer needed.
+ * w32.h (DEF_DLL_FN, LOAD_DLL_FN): New macros.
+
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
