(svn r828) Everyone welcome table/sprites.h in trunk - so far not in use besides enum AnimCursors migrated from viewport.h and tiny fragment of enum Sprites migrated from ttd.h (we should slowly convert trunk to use the symbolic names instead of sprite numbers too to reduce the delta to map). Ported from the map branch, where the work was done by Darkvater, Celestar and Tron.
#include <stdio.h>

// This pretty simple file checks if the system is LITTLE_ENDIAN or BIG_ENDIAN
//  it does that by putting a 1 and a 0 in an array, and read it out as one
//  number. If it is 1, it is LITTLE_ENDIAN, if it is 256, it is BIG_ENDIAN
//
// After that it outputs the contents of an include files (endian.h)
//  that says or TTD_LITTLE_ENDIAN, or TTD_BIG_ENDIAN. Makefile takes
//  care of the real writing to the file.
