Just for the record:

The Windows build does *not* handle changed .h files and .h fie 
dependencies when deciding what needs to be recompiled.

So: if a .h file is changed, then either a complete rebuild is needed or 
 you must manually force a recompile for any .c files using the .h file 
(E.G.: by deleting the .obj files corresponding to the .c files).

Doing this manually can easily miss something so use the manual 
procedure only if you are exactly sure what needs to be recompiled when 
a .h file changes.
