I vaguely remember, that some time ago, a discussion took place,
whether it is possible to fold a C source, so that only the relevant
lines are visible and the parts in #ifdef's, that are not defined are
hidden. Example:

#ifdef USG
uname(...);
#else
hostname(...);
#endif

should show only

uname(...);

resp.

hostname(...);

depending, whether I tell the function USG is defined or not.

Has there been any conclusion? Or even an emacs lisp function for
that?
