Macro Indicating NIOS Compilation?

[Altera_Forum]

In my code I can do something like: 

  # ifdef _WIN32 .... # endif   To only include code on a Windows target. Is there a similar symbol that is automatically defined by the NIOS IDE when compiling? I am making a library that I am debugging on Windows and would like to include both NIOS and Windows code separated in this manor, and I would prefer an automatic symbol over a custom made one.

You can define any symbol you want in the build->preprocessor options. 

If you don't want to add extra symbols and use default project settings, I think you can exploit ALT_DEBUG and ALT_RELEASE.

RTFM: 

 Try: gcc -E -dM empty_file.c  __NIOS2__
