I'm sorry, but I did try "arm-wince-mingw32ce-g++ -v".
I get NO flags listed.
It seems that there is a really significant difference betwwen "cegcc" and
"mingw32ce" compilers.
Now I can see that "arm-wince-cegcc-g++ -dumpspecs" produces CORRECT
result, while ""arm-wince-mingw32ce-g++ -dumpspecs" does NOT.

Yes, but today's include files just check whether these variables are
defined. They do not check the value. So, adding a value would not break
anything.
The problem with a new include file is that there is no way to test
whether it exists in advance. If one puts "#include <cegcc.h>" and the
file does not exist, one is lost.
That is why I am trying to find a solution which will be backwards
compatible - i.e. it uses an existing include file (which would then
include the cegcc.h automatically) and/or an existing macro.
A solution would be to add another macro to predefined macros.
Something like "__HAVE_VERSION__" (defined automatically by the compiler,
not by an include file). Then one could do:
#ifdef __HAVE_VERSION__
#include <cegcc.h>
#endif
