[boost] [gil::io] Compilation issue

Hi all, my metaprogramming zen is failing me and I like to ask for some help. Using gil's updated develop branch the following code creates a compilation error with Visual Studio 2015 Update 3. #include using namespace std; using namespace boost; using namespace gil; int main() { gray1_image_t img; write_view( "", view( img ), tiff_tag() ); return 0; } The compiler output is here: https://pastebin.com/raw/d1AB9QMz I think the error is in https://github.com/boostorg/gil/blob/develop/include/boost/gil/premultiply.h... but I'm not sure what to do. Any help would be very helpful! Thanks, Christian
