Very true - horse, water, drink.

One of the public APIs we support largely uses ‘long’ and ‘unsigned
long’ for integral values, which causes occasional issues with our
cross-platform code. For example ‘unsigned long’ has the same size as
‘size_t’ on Linux, but not on 64-bit Windows.

Which is why putting assigning the value of a size_t to an unsigned
long or vice-versa is wrong. But hey early C programmers used to store
pointers in ints (there's a moan about it in first edition K&R *that*
early).
