I added the discussed preprocessing hooks to the Wave library (see the Boost
CVS::HEAD). Additionally I added a new sample application demonstrating the
new hooks (it's called advanced_hooks). This sample outputs not only the
preprocessed tokens, but additionally any conditional directive found and
the complete non-expanded source code from false conditional blocks. I.e.
for the following snippet

    #define TEST 1
    #if defined(TEST)
    "TEST was defined: " TEST
    #else
    "TEST was not defined!"
    #endif

the generated output looks like:

    //"#if defined(TEST)
    "TEST was defined: " 1
    //"#else
    //"TEST was not defined!"
    //"#endif
