/* The next one is to avoid having SymbianCommonGenerator as a virtually
inherited class of this class. Instead it is without a base class
(avoiding the virtual inheritance problem), and is allowed to use
functions defined in here.
To illustrate:
+-------------------+
| MakefileGenerator |
+-------------------+
^ ^
| |
| X <-- Avoid this inheritance
| |
+------------------------+ +------------------------+
| UnixMakefileGenerator | | SymbianCommonGenerator |
| or | | |
| NmakeMakefileGenerator | | |
+------------------------+ +------------------------+
^ ^
| |
| |
| |
+-----------------------------+
| SymbianMakefileTemplate<> |
+-----------------------------+
We want to avoid the famous diamond problem, because if we have that, we need
virtual inheritance, which not all compilers like. Therefore, we break the
link as illustrated. Instead, we have a pointer to MakefileGenerator inside
SymbianCommonGenerator, and allows full access by making it a friend here.
