allow setting of variables. This has to do with making the library
re-entrant. The variables do not exist, but code that refers to them
still works because the variable names are defined as macros that call
functions that retrieve the value. For some of the variables, it
doesn't even make sense to set the variables, and we assume few programs
ever exploited this ability, so simply removed it by default for
everyone starting with the January 2010 release.
If you have an old Ncurses library that allows setting of variables
and really want this function in Curses.pm, #define ALLOW_VARS_STORE
in your c-config.h.
