CRITICAL BUGS in this setup that needs to be fixed:

- config.h contains the define "COIN_SYSTEM_LIBRARY_NAME" that needs to be
set different for debug and release builds.  Need to figure something out
for this one.

- sowin1.dsp/vcproj and soqt1.dsp/vcproj link both with coin2d.dll in
both debug and release build modes.  Should not be too hard to fix.
