[ODE] ODE on Pocket PC

[George Birbilis]

btw, I think some Pocket PC platforms are 16-bit and default settings may
not be aligning structures to 2-byte boundaries or even not aligning
structures at all (at 32-bit platforms you usually align at 4-bytes [#pragma
pack, or #pragma align, or something like that I think]). So might it be
related to some data alignment setting?
