Sample code

The attached test file produces with "g++ -c test.cc" of GCC version 4.7 (e.g.
the one shipped with OpenSuse 12.2) and 4.8 the following output:

test.cc: In constructor 'C_DrvDataBuffer::C_DrvDataBuffer(ushort, ushort)':

The test code can be compiled with the Comeau-Online-Compiler:

The GCC 4.6 works also.
