Here's a really ugly perl script that traverses a set of directories and
pulls out HAVE_* symbols from .h/.c/.cpp files and then prints out what
files they occur in.  Call it like this

% find-config-symbols.pl kdelibs

Here's sample output run against the dcop directory:

% find-source-files.pl dcop
HAVE_CONFIG_H
  dcop/dcopserver_shutdown.c
  dcop/dcopserver_shutdown_win.cpp
HAVE_LIMITS_H
  dcop/dcopserver.cpp
HAVE_MKSTEMPS
  dcop/dcopserver.cpp
HAVE_SYS_PARAM_H
  dcop/dcopserver.cpp
HAVE_SYS_SELECT_H
  dcop/dcopserver_shutdown.c
HAVE_SYS_STAT_H
  dcop/dcopserver.cpp
HAVE_SYS_TYPES_H
  dcop/KDE-ICE/Xtrans.h
  dcop/dcopserver_shutdown.c
  dcop/dcopserver_shutdown_win.cpp

Hope this is useful.  Note that running it against all of kdelibs
will probably take a long time (10-20 minutes, I'd estimate).

Cheers,
Tanner
