C++'s long and unsigned long can be accessed with c_long and

underlying types.
Meaning that there is no way to interface to a C++ function
declared as:
void foo(unsigned long);
So, what to do about this?
1. elevate c_long and c_ulong into full fledged types.
2. create full fledged types __c_long and __c_ulong, and alias
c_long and c_ulong to them.
Having actual new types makes me a bit nervous in regards to how
overloads will be handled, and how templates will be instantiated.
I don't know how things happen behind the scenes, but (as I
remember), writing "portable" C++ code to handle all possible
integral primitives was a real hell, as on some systems,
"foo(int)/foo(long)" would collide, whereas on others, you *need*
both declared.
Will this start happening in D too now...?
