14Abstract:
15
16 This file turns 4 byte packing of structures on. (That is, it disables
17 automatic alignment of structure fields.) An include file is needed
18 because various compilers do this in different ways. For Microsoft
19 compatible compilers, this files uses the push option to the pack pragma
20 so that the poppack.h include file can restore the previous packing
21 reliably.
22
23 The file poppack.h is the complement to this file.
