Funny.  It doesn't get shadowed here.

But I've never got around to make `hide-ifdef-mode' work reasonably with
the Emacs code base.  I suppose that I'd have to set up some definitions
manually, then scan config.h and then scan the remaining header files in
the order they were processed by the compiler.  So if you could come up
with a solution, this would be very much appreciated here.

BTW, `hide-ifdef-mode' fails on my current config.h file with the trace
below.
