7 | /* This file describes the "global" variables used by perl | |
8 | * This used to be in perl.h directly but we want to abstract out into | |
9 | * distinct files which are per-thread, per-interpreter or really global, | |
10 | * and how they're initialized. | |
11 | * | |
12 | * The 'G' prefix is only needed for vars that need appropriate #defines | |
13 | * generated when built with or without EMBED. It is also used to generate | |
14 | * the appropriate export list for win32. | |
15 | * | |
16 | * Avoid build-specific #ifdefs here, like DEBUGGING. That way, | |
17 | * we can keep binary compatibility of the curinterp structure */ | |
