+# MKncurses_def.sh -- generate fallback definitions for ncurses_cfg.h
+#
+# Author: Thomas E. Dickey <dickey@herndon4.his.com> 2000
+#
+# Given the choice between constructs such as
+#
+#      #if defined(foo) && foo
+#      #if foo
+#
+# we chose the latter.  It is guaranteed by the language standard, and there
+# appear to be no broken compilers that do not honor that detail.  But some
+# people want to use gcc's -Wundef option (corresponding to one of the less
+# useful features in Watcom's compiler) to check for misspellings.  So we
+# generate a set of fallback definitions to quiet the warnings without making
+# the code ugly.
