Hermès Bélusca-Maïto 2672ec8ee5 [SOFT386] 
- In the interface header soft386.h, do not include other particular headers (windows.h and debug.h). Those must be included by the different applications which also will include soft386.h.
- LPVOID --> PVOID (do it general, not just à-la Win32).
- The .c files include the headers, and each .c files must have its "#define NDEBUG\n#include <debug.h>" lines, to activate (or deactivate here in the example) debugging output.
- In the .c files, include the header windef.h for having the basic types, and temporarily comment out the needed #defines which will be needed if one needs to include other win***.h files. Those will be deleted if they aren't needed at the end.
