11 | * When building without USE_THREADS, these variables will be truly global. |
12 | * When building without USE_THREADS but with MULTIPLICITY, these variables |
13 | * will be global per-interpreter. |

15 | * Avoid build-specific #ifdefs here, like DEBUGGING. That way, |
16 | * we can keep binary compatibility of the curinterp structure */ |
