Dear cygwiners,

I managed to patch most of the headers from the latest Platform SDK to
make them useable for gcc (i.e., the preprocessor doesn't produce errors).

However, I came across the following problem: 

A lot of header files typedef some symbols more than once, thus producing
warnings like

 ... Warning: redefinition of blah_blah ...
 ... blah_blah previously defined in ...

Is there a way to avoid these warnings that is not contained in the following
list:

- adding for each typedef something like #define blah_blah_defined and
  checking #ifndef blah_blah_defined ... #endif 
- forgetting about the Microsoft headers
- closing my eyes during preprocessing and ignoring the warnings

Any suggestions appreciated,

    Axel
