I successfully compiled a game I wrote using BC++ 3.1 a year or two ago using 
DJGPP+RSXNTDJ, demonstrating that fairly complex programs can be produced 
using these tools.  The program only used core Win32 functions, however, so 
its probably not a fair indication of the capabilities and shortcomings of 
RSXNTDJ.  In addition, the tests included in the package demonstrate the use 
of the common dialogs, toolbars, etc., so a fair bit of functionality does 
work.

I have read in other threads that RSXNTDJ does not support C++, which (if 
true) is a pretty major shortcoming, as C++ is becoming more important for 
Windows programming.  It also lacks support tools, such as a debugger and 
profiler, which is where Cygnus has a distinct advantage (despite all Cygnus 
programs relying on a 3Mb DLL).

As for MFC, I believe it could be used (with great difficulty) if C++ support 
was added to RSXNTDJ, as you can use the makelib utility included in the 
package to export the appropriate functions from the various MFC DLLs.  The 
headers and so on would be more of a problem, but I'm sure someone somewhere 
has access to VC++!  :-)

Anyway, hope this helps clear things up a little,

Peter
