You would want the "int" between angular brackets to be colored
green, like any other type?  Adding the following line to your
~/.nanorc should partially achieve that:

  extendsyntax c color green "<(bool|enum|float|wchar_t|((un?)signed )?(long 
|short )?char|double|int)>"

But it colors the angular brackets green too, which is not nice.

So better would be to... not "allow" comments after include
statements: add a "$" at the end of the string coloring rule,
so only strings of the form <word> at line's end get colored.

color brightyellow ""([^"]|\\")*"" "<[^[:blank:]=]*>$"
