You need to link against the libraries containing all the symbols you're
using, this is Windows, no undefined references allowded here.
Try:
gcc -g -Wall -ansi -pedantic -Wwrite-strings -Wshadow
 -Waggregate-return -I. -I/cygdrive/d/Data/calendar/include
 -I/usr/include/ncurses -I/usr/local/include
 -c output.c -o oncurses.o
 
gcc -g -shared -o ../cygoncurses.dll \
 -Wl,--out-implib=liboncurses.dll.a \
 -Wl,--export-all-symbols \
 -Wl,--enable-auto-import \
 -Wl,--whole-archive \
 oncurses.o \
 -Wl,--no-whole-archive -L/usr/lib -lintl -lncurses
And probably some more libs missing at your link line.
HTH,
Gerrit
