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.
