Actually, you can't do it in config.h.  It's a common limitation, since 
the directories are usually left defined as something like 
"${prefix}/share".  From the autoconf docs:

	A corollary is that you should not use these variables but in
	Makefiles.  For instance, instead of trying to evaluate `datadir' in
	`configure' and hardcoding it in Makefiles using e.g.
	`AC_DEFINE_UNQUOTED(DATADIR, "$datadir")', you should add
	`-DDATADIR="$(datadir)"' to your `CPPFLAGS'.
