7/* The 'T' prefix is only needed for vars that need appropriate #defines
8 * generated when built with or without USE_THREADS. It is also used
9 * to generate the appropriate export list for win32.
10 *
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.
14 *
15 * Avoid build-specific #ifdefs here, like DEBUGGING. That way,
16 * we can keep binary compatibility of the curinterp structure */
