I did some work to excise the enhanced curses stuff from the
!HAVE_WCHAR build last November but got distracted.

I have just fixed the DISABLE_WCHAR build (I did all the preparatory
work on attributes.c and then never got around to add the ifdefs,
sorry).

On amd64 I get:

   text    data     bss     dec     hex filename
 158202    7112    8200  173514   2a5ca libcurses.so.8.2 # normal
 109868    4546    2080  116494   1c70e libcurses.so.8.2 # DISABLE_WCHAR


or, probably more relevant for sysinst, for the .a files:

   text    data     bss     dec     hex filename
 111275    4126    2405  117806   1cc2e (TOTALS) # normal
  76231    2078    1379   79688   13748 (TOTALS) # DISABLE_WCHAR

So about 36K.  Actual savings will be less since sysinst likely
doesn't pull in all of it.
