Changed the type of a compiler variable that holds either integers or pointers.
...
The change allows cc65 to be compiled on 64-bit Windows, without getting warnings. That OS is actually 32 bits with 64-bit pointers. Its pointers are "long long" instead of "long". The change uses type-names that are configured for the actual pointer width.

Changed the low level type representation from a strung of unsigned short
...
elements to a string of structs, each representing one type element. This
should fix problems on unusual architectures, since it is no longer necessary
to embedd pointers and other data converted to numbers in the string of
unsigned shorts.
Increased the TypeCode length to unsigned long to make room for more type
bits.
Inline more functions in datatype.h.

When assigning structures, copy them using the primary register when the
size is 1, 2, or 4.
When assigning structures, allow structures by value when the size is 1,
2, or 4. These structures are expected to be in the primary register. The
only case when this can happen is by return from function, so this change
makes div() work.
