But does it work without pkg-config?  I suspect that it will throw an
error message complaining that pkg-config is not available.

There is another problem as well... If I install my own, local copy of
libncursesw in to, say, ~/mylibs/myncursesw and then try to go like
this:

  $ ./configure "LDFLAGS=-l$HOME/mylibs/myncursesw"

it will not work.  pkg-config will use the library that the system
knows about instead.  There is an interesting post about it here[1].
The same post also suggests a way to use PKG_CHECK_MODULES, which we
discussed before, that is "correct":

  1. invoke AC_CHECK_LIBS *first*, so that the "usual" mechanisms are
  given a chance to work.

  2. if that fails, invoke PKG_CHECK_MODULES

  3. if that succeeds, invoke AC_CHECK_LIBS again, in case pkg-config
  returned something invalid.

I agree with you, though -- step 3 probably isn't too important.  But
would you mind changing your fix to run AC_CHECK_LIBS first, and then
PKG_CHECK_MODULES on failure?  I think that would be a better solution.
