I have also added HAVE_WCHAR ifdefs to slk.c, which I forgot about.
From a quick visual inspection the DISABLE_WCHAR curses no longer
refers to anything untoward.

HAVE_WCHAR curses additionally refers to:

+                 U __setlocale50
+                 U btowc
+                 U fgetwc
+                 U fputwc
+                 U iswprint
+                 U mbrtowc
+                 U nl_langinfo
+                 U strcasecmp
+                 U wcslen
+                 U wcsrtombs
+                 U wcwidth
+                 U wmemchr
+                 U wmemcpy

so i guess not pulling in that stuff from libc should help to reduce
the size of the program binary.
