It is actually code handling some endianness stuff.

Maybe a template function would be more appropriate, avoiding possibly 
dangerous conversions by putting a static assert into the default 
implementation. But I'd still have to provide specializations for 
uint32_t and unsigned long or uint32_t and unsigned int, depending on 
the platform.

Ideally, I'd like to work only with those fixed width integers if I need 
to provide an implementation for every integer type, avoiding code noise 
with ifdef and co.
