Fix compiler warnings about not used dummy() functions
It has been reported that the Microsoft Visual C compiler complains if a .c file do not contain any compilable code, which can happen if the code has been #ifdef'ed out. To avoid this, these #ifdef sections have a #else section which adds a static dummy() function which does nothing. On the other hand, the GNU C compiler complains about unused functions when it discovers this situation. This patch tries to only add these dummy() functions if the Microsoft Visual C compiler is detected, via the _MSC_VER macro.
