>Description:
	unifdef -t seems not to work in FreeBSD 4.8.  The version in 4.7
	doesn't seem to have the problems I'm seeing (see below).
>How-To-Repeat:
	The following trivial example dumps core for me.

	  $ unifdef -t -DFOO <<%%
	  #ifdef FOO
	  foo
	  #endif

	Other incantations I tried just fail to process the #ifdefs.
>Fix:
