FYI, Wave has a special #pragma usable for bridging this gap:
#pragma wave system(any OS command)
which spawns of the given command and intercepts the produced stdout stream, inserting it instead of the pragma itself :-P. In C99 mode you even may use it from the operator _Pragma and force a full macro expansion of the inserted results:
#define EVAL(x) x EVAL(_Pragma("wave system(any OS command)"))

Hartmut,
is that a good idea? I can imagine that running an existing executable might cause untold damage to my system, but compiling a piece of source code?
Doesn't it smack of C++ source code as computer virus?
Well, you still need to have the 'appropriate' executable to run to make it into a virus. And, BTW, this was a feature request for Wave during its development. But I may include the corresponding code based on a preprocessor directive only, so by default this wouldn't be compiled in ... :-P Regards Hartmut
