Hello,
I've investigated this problem a little bit more and have found a
solution (patch attached). It looks simple but has driven me crazy.

I'm afraid this won't work because sizeof is unknown to preprocessor.
I played around with UINT_MAX and ULONG_MAX but that also doesn't work.
Then I found that the size of the types doesn't matter at all. The
internal names of the types are important. They are not allowed to be
equal.
size_t is typedef from 'unsigned long' on 64bit systems and 'unsigned
int' on 32bit systems. 'unsigned long' is ok but 'unsigned int' gives
a problem because it is equal to the following instantiation.
On OpenBSD size_t is always typedef from 'unsigned long', even on 32bit.
That's why the problem doesn't exist under OpenBSD.
Finally I adopted the OpenBSD solution to the other platforms. I did it
by replacing size_t with 'unsigned long':
__instantiate(Vector<unsigned long>)
__instantiate(Vector<unsigned int>)
Now it runs on all platforms and a preprocessor directive is not even
needed.
Best Regards, Ulrich
