Ton Roosendaal 02b2fc5ec8 Added warning in makesdna to check for total struct sizes. 
Found error in wipe struct, which was even constructed terrible weird :)

*
* Struct muncher for making SDNA
*
* Originally by Ton, some mods by Frank, and some cleaning and
* extension by Nzc.
*
* Makesdna creates a .c file with a long string of numbers that
* encode the Blender file format. It is fast, because it is basically
* a binary dump. There are some details to mind when reconstructing
* the file (endianness and byte-alignment).
*
* This little program scans all structs that need to be serialized,
* and determined the names and types of all members. It calculates
* how much memory (on disk or in ram) is needed to store that struct,
* and the offsets for reaching a particular one.
*
* There is a facility to get verbose output from sdna. Search for
* debugSDNA. This int can be set to 0 (no output) to some int. Higher
* numbers give more output.
* */
