This package was built by Evin Robertson using cygwin b20.1, available
from cygnus's web page.  Instructions follow if you want to build
nitfol yourself from source, which will be available from
http://ifarchive.org/indexes/if-archiveXinfocomXinterpretersXnitfol.html

Nitfol 0.5 doesn't build for windows straight from the source (I'll
try to fix this for 0.6).

You'll need winglk.  Unpack it and do:
dlltool --as=as --dllname=glk.dll --def=glkdll/glk.def --output-lib=libglk.a
echo GLKLIB=-lglk > Make.winglk

In nitfol's makefile, change ALLFLAGS to -mno-cygwin, and add
-Wl,-subsystem,windows to LDFLAGS.  Remove -ansi from CFLAGS.

In startwin.c, remove all bits referencing to stdio and printf.  If
you want nitfol.cfg support, copy it in from startdos.c, using
n_file_name() in place of glkunix_stream_open_pathname().

Type 'make winnitfol'; winnitfol.exe should appear.

If I've remembered everything, this should mostly work.  If you run
into difficulties (but you are able to compile and run the example Glk
apps), let me know.
