I don't believe you can change the contents of DGROUP without producing
intermediate assembly code, modifying it, and then using the Microsoft Macro
Assembler.  But don't expect any other Microsoft programmer's aids to work on
the resulting executable.

If DGROUP is too crowded, you could reduce stack space (within reason) by
using command line linker options, or use the -Gt compiler option to reduce the
size threshold at which aggregate objects are sent to far data segments.
