While we are at it, there *is* an obvious workaround:
#ifdef ...
#define L1 <list>
#else
#define L1
#endif
#ifdef ...
#define L2 <list>
#else
#define L2
#endif
your_macro(...
L1
L2
...)
#undef L1
#undef L2

Ingo, care to explain what the hell had your reply above been about?
Especially since we both apparently agree that code in question did
need fixing, what with your immediate ACK upthread...
