I think we do, right?  I mean, we check for tgetent in configure.
What did configure say when you ran it without ncurses-devel installed?

You want to look at dtimep.c (the generated output from dtimep.lex).
And from the 1.4 tarball ... yes, it's in there.  Well, specifically,
there is this:

#define YY_DECL struct tws *dparsetime(char *lexstr)

And YY_DECL is used as a function prototype later for the scanner.  So
I'm puzzled by this one.
