Fix VisualC++ build (Visual Studio 2015).

IDE generated with CMake, still many warnings, but compiles and runs.

Note: we *must* get rid of all VisualStudio-specific #define's like:

 #define unlink _unlink

This one led to a compilation error (not a warning).

src/Fl_File_Icon.cxx: I had to add _MSC_VER (WIN32) distinction as in
  previous code (FLTK 1.3). Obviously MinGW is more Unixy than MS VC++
  since MinGW compiled and linked the code. Needs a better fix ...
