from the previous discussions about C++ there was some consensus not
to introduce C++ intro GRASS directly. But: GDAL contains a C wrapper
around the C++ functions which are needed for the interface (called
"GDAL bridge"). 
Laura, maybe you can wrap the interfacing functions of your code to C?

The same we expect for OGR (the vector counterpart for GDAL raster),
a C wrapper ("OGR bride" or so). Frank Warmerdam has developed the
GDAL bridge. It's part of GDAL (subdirectory bridge):
http://remotesensing.org/gdal/

I am rather sure that core GRASS remains C, but such wrappers may
establish the connection to C++.

There is also the "libgrass" containing I/O routines of GRASS (the related
C functions extracted for that package). I am using that for
GRASS/MapServer.

Maybe the other developers have a different opinion?!
