Here's a more general question related to my other question about huge
pointers and Globally Allocating (sic) memory.

When the documentation says that you have a 4 Gig address space in 386
Enhanced mode, how's it doing that?  The MS C compiler is only making
16 bit code and not using the 32 bit segment registers on the 386, so
what gives?  I guess the Windows Global heap might be using a 32 bit
register, but how's it getting a 32 bit pointer back into the MS C
compiled application?

Thanks in advance,
