Comment (by Roland Haas):

Actually Cactus itself contains such a check in `src/include/cctk_Types.h`:

``` /* Determine whether we have a traditional or an ANSI cpp. */ #ifdef FCODE /* The empty comment in the definition of CCTK_ANSI_FPP will either turn into nothing or into white space. There must not be any add spaces around this empty comment.

A traditional cpp will turn it into nothing, an ANSI cpp will turn it into white space. Depending on this, CCTK_ANSI_FPP will either turn into a single separate token (which lead to the value 0), or into two separate tokens (which lead to the value 1).

This is magic. */ #define CCTKi_FPP_A #define CCTKi_FPP_B 1 #define CCTKi_FPP_ACCTKi_FPP_B 0 #define CCTK_ANSI_FPP CCTKi_FPP_A/**/CCTKi_FPP_B #endif ```

so really it should support both. Namely if code fails if `FPP` is not traditional then that could should be changed so that it works both with and without traditional.
