[dba-Tech] TIOBE Programming Community Index for May 2013

 Hi Jim --

Yes, it does - AFAIK there exists a common Windows API subset:

http://blogs.msdn.com/b/b8/archive/2012/02/09/building-windows-for-the-arm-processor-architecture.aspx

+ you use native C/C++ compile time features:

- #define statement, 
- conditional compilation, 
- templates etc. 

to build your app version to be run on a specific Windows platform.

Thank you.
