Asserts breaks ode in different archs

[Leopold Palomo-Avellaneda]

With the changes made in:

ode/ode/src/typedefs.h

ode is broken in some archs that worked before:

https://buildd.debian.org/status/fetch.php?pkg=ode&arch=x32&ver=2%3A0.16-1&stamp=1547237069&raw=0

this is really necessary?

Please check the latest commits -- all has to be fixed. Alas, I have no hardware/systems to test it.
