     24 /* What all this is for? Well, it's simple...
     25  * Example: When someone compiles a module with ssl support, but the
     26  * core was not compiled with ssl support, then the module will read
     27  * things incorrect in the struct because the module sees an extra
     28  * field half-way the struct but in the core that field does not exist,
     29  * hence all data is shifted 4 bytes causing all kinds of odd crashes,
     30  * memory corruption, and weird problems.
     31  * This is an attempt to prevent this a bit, but there are a lot more
     32  * options that cause binary incompatability (eg: changing nicklen),
     33  * we just take the most common ones...
     34  *
     35  * NOTE: On win32 we allow ssl inconsistencies because we
     36  *       explicitly use "padding" in the structs: we add a useless
     37  *       placeholder so everything is still aligned correctly.
     38  *       In the process of doing so, we waste several bytes per-user,
     39  *       but this prevents (most) binary incompatability problems
     40  *       making it easier for module coders to ship dll's.
