#include "version.h"
/* What all this is for? Well, it's simple...
* Example: When someone compiles a module with ssl support, but the
* core was not compiled with ssl support, then the module will read
* things incorrect in the struct because the module sees an extra
* field half-way the struct but in the core that field does not exist,
* hence all data is shifted 4 bytes causing all kinds of odd crashes,
* memory corruption, and weird problems.
* This is an attempt to prevent this a bit, but there are a lot more
* options that cause binary incompatability (eg: changing nicklen),
* we just take the most common ones...
*
* NOTE: On win32 we allow ssl inconsistencies because we
* explicitly use "padding" in the structs: we add a useless
* placeholder so everything is still aligned correctly.
* In the process of doing so, we waste several bytes per-user,
* but this prevents (most) binary incompatability problems
* making it easier for module coders to ship dll's.
