fp_utils.cc error C3861 : 'ilogb' : identifier not found

[GoogleCodeExporter]

I am trying to build or-tools from source :
svn checkout http://or-tools.googlecode.com/svn/trunk/ or-tools-read-only

On Windows 7, 64 bits.
With VC++ 2012.

Building dependencies was fine.

But when building the core :
> make cc java 

I get the following error :

cl /EHsc /MD /nologo -nologo  /O2 -DNDEBUG /Isrc /Iexamples /Isrc\\gen

Hi, 

Can you switch to visual studio 2013?
ilogb seems only supported from that version.

I dropped support for visual studio 2012.
