I suspect the library, as opposed to the header, actually does.  The
rule in terminfo.mdd is that the file is only compiled if
tigetflag is found; it doesn't bother checking for all the
tiget... functions since either all or none should be available.  This
suggests it's only the header that's defective, or at least not what the
configuration is assuming.  This changed in 4.2; before that the tests
were a bit more hit and miss.
