compile on windows ('mapnik::svg::grammar::parse_rule()': function template has already been defined (compiling source file ..\..\src\svg\svg_path_grammar_x3.cpp))

Hi,
While I want to compile mapnik on windows with VS 2015 but I get this error

Severity	Code	Description	Project	File	Line	Suppression State
Error	C2995	'bool mapnik::svg::grammar::parse_rule(unknown-type,Iterator &,const Iterator &,const Context &,Attribute &)': function template has already been defined (compiling source file ..\..\src\svg\svg_path_grammar_x3.cpp)	mapnik	E:\Personal\Project\MApnik\windowsBuild\windows-builds\packages\mapnik-master\include\mapnik\svg\svg_path_grammar_x3_def.hpp	186	

and this

Severity	Code	Description	Project	File	Line	Suppression State

can some one helps with this problem?

@am2222 VS2015 is not able to compile latest master of mapnik because of the latest C++ features mapnik uses.
Currently we are transistioning the build scripts to VS2017 - although this might still take a few weeks.

mapnik@v3.0.x might still work with VS2015, but I haven't check lately.

To use that branch call settings.bat like this:

settings "MAPNIKBRANCH=v3.0.x"

thanks very much, I'll try that branch.
