[igraph] [R-igraph_0.5.3/Win] Error during compilation - encoding.h is "missing"

[Łukasz Ręcławowicz]

Hi,

I got this error:

foregin-graphml.c:35:22: fatal error: encoding.h: No such file or directory
compilation terminated.

This file is in \libxml2-2.7.6.win32\include\libxml.
foregin-graphml.c looks like this
34 #if HAVE_LIBXML == 1
35 #include <libxml/encoding.h>
36 #include <libxml/parser.h>
