OK, tracing back to the MS documentation it seems that a DWORD_PTR is
unsigned 32- or 64-bit int, but due to the MS htmlhelp.h redefining it as DWORD
on 64-bit arcitectures, (which seems a kludge to hide the fact that this 
parameter
should not have been defined as DWORD_PTR in the first place) it is basically
always an unsigned 32-bit int.

So defining it as DWORD should actually work in all cases.

I propoe we simply define it as DWORD, and never mention DWORD_PTR anywhere.
