CFront doesn't define anything; it works on preprocessed C.  OK,
I'm being a pedant :-)  However, my real concern is that I have
c++ version 3.1, and this doesn't define |c_plusplus|.  It
generates command lines of the form

  cc -C++ -D__cplusplus -E  c++.source > scrapfile

You would need to check which CPP is being used.  This could be
done by checking for |__CC_NORCROFT|.  However, I believe the ARM
compiler suite was derived form the Norcroft one.  Does the ARM
C++ compiler define |__CC_NORCROFT|?  I am tempted to request a
copy of the ARM Developer Suite evaluation CD, just to get at the
documentation.
