We just traced a wierd bug.  After some debugging it turned out that parts
of the code was not compiled. The code was something like:

#ifdef	/* FLAG */
	do_something();
#endif

Obviously the source was compiled with -DFLAG. The code between the #ifdef
and #endif was not included in the compilation and everyone looked over this
error (?). The compiler gave no warnings or errors, but I think it should do
so in this case as an 'ifdef' always requires an identifier, or do I miss
something ? I also tried just a plain '#ifdef' on a line and this too is
accepted by our compiler (i.e. code is not included in the compilation).
