Fix Visual Studio shared library build

Browse Source 
Todo: fluid-shared can't (yet) be built agains the shared fltk lib
  because of some linker errors. Needs investigation.

Note: fluid-shared is basically a test program to demonstrate linking
  against the shared FLTK libs but doesn't work yet using VS (MSVC).
  This is no problem for the functionality.
