Thanks Jacques, that probably explains everything.

It seems by adding "/3GB" parameter in boot.ini, you can set the kernel 
to allocate only 1 GB of virtual memory, thus giving the user's programs upto 3
GB of virtual memory. 32-bit applications on Windows x64 will get the full 4 GB
without needing any special boot parameters.

This is all assuming that the applications were compiled using a "Large Address
Aware" flag. With this said, I think EXW/EXWC.exe would need to
be compiled with that flag; EMAKE.bat would need to have it for building Windows
translated apps. Unfortuantly, I dont know what the Watcom, Borland, and LCC
equivalent of "/LARGEADDRESSAWARE" is. :/
