It's the invocation of aray new inside CArray<>

My afxtempl.h is too heavily patched to know what line 305 is...

 ?_P is array operator new.


Interesting. This is all working with lots of other compilers, but I decided 
to try and bring DMC++ back into the MFCSTL fold in my unit-tests but this 
is what crops up. I have no idea why this error should crop up. I suspect 
that the compiler's mistaken, and there's something else going wrong.
