Boost Preprocessor - Nested repeat?

I have what looks like a perfect application for Boost/Preprocessor. 
I have 192 entries in a Factory Map a portion of which are show 
below. I'd like to generate the permutations of the three macro 
inputs, but can't figure out where to start. Any help would be 
appreciated.

#define MAP_ENTRY_MCR( aLang, aType, aAcc ) \
\
mMap[ CKey( aLang, aType, aAcc ) ] \ 
= CVarX< aLang, aType, aAcc >::Make;

   MAP_ENTRY_MCR( DCTlanguageC, DCT_DOUBLE , DCT_NONE    );
   MAP_ENTRY_MCR( DCTlanguageC, DCT_DOUBLE , DCT_INIT    );
   MAP_ENTRY_MCR( DCTlanguageC, DCT_DOUBLE , DCT_ANYTIME );
                                                
   MAP_ENTRY_MCR( DCTlanguageC, DCT_FLOAT  , DCT_NONE    );
   ...

Thanks, Jeff Flinn
