C++ - Sorry, Slightly off-topic

[Sabatke, Jim]

I have been trying to compile Lilypond with MSVC and Watcom C++ on my PC.  I
am an old C programmer, but am relatively new to C++.  The Lilypond lib uses
a construct that is not recognized by either compiler: They are >? and <?. 

Are these standard C++?  What are they?

Thanks,
