For clearness I decided to add a quick lecture.  Hope that's ok.
Makes much sense. I would suggest two additions:

...
- DON'T mix up int and long in printf/scanf.  This:

     int i; long l;
     printf ("%d %ld\n", l, i);

   may not print what you think it should.
- DON'T forget to enable -Wformat gcc warnings, try also -Wformat=2.

(-Wformat is included in -Wall, -Wformat=2 is neither included in -Wall nor in -W[extra]).


...
- DON'T use C base types together with Win32 functions.  Keep in mind
   that DWORD, LONG, ULONG are *not* the same as long and unsigned long.
   Try to use only Win32 datatypes in conjunction with Win32 API function
   calls to avoid type problems.
- DON'T forget to add casts if such Win32 API types are used with 
printf(). This:
  printf("Win32 Error=%lu\n", GetLastError());

worked for all i686 and Windows x86_64, but fails now on Cygwin x86_64.
