Preprocessor Macros for C

[Michael Rufer]

I need to define some preprocessor macros for C , because the source code has some none ansi C constructs for interrupt handling.
The parsing fails because of these constructs.

When I open the "Preprocessor Macros" menu from the settings i can not select the C language from the dropdown and therefore also not define any macros.

Is there a reason why C language should not be available as selection?

I believe it uses the same macros as C++.
