Compile the C++ parser library with Sun CC 5.9.

Things you mustn't do:
1) end an enum with a comma

2) #include <cxxxx> and not use std::

3) use anonymous structures

All three things are invalid C++. Anonymous structures inside
anonymous unions are allowed by GCC, but that doesn't mean it's valid.
