No, because the headers that came with 5.7-2 had macros that turned his
code 'curscr' into 'ncwrap_curscr()'.  In the briefly released 5.7-1 the
macros turned 'curscr' into '_nc_curscr()'.  So, the only way his object
code would be "looking" for the symbol "_curscr" would be if he was
using the headers from ncurses-5.5-3 or older.  But the headers and
import libraries are distributed in the same package; it's not possible
to have the headers from one release and the import libraries from a
different one.

Unless you do
$ gcc -o foo.o -c foo.c

and then upgrade ncurses-devel, before doing
$ gcc -o foo.exe foo.o -lncurses

But Alexey did the compile and link all in one command.  That's a REALLY
fast setup.exe...

That's why I was confused.  But, 'tis working now, with 5.7-3. So...
