i've got five files here, which are attached.  it's a program called
SimpleWindows,
which allows the user to program to windows and display it in a simple
window.
I downloaded Rsxntdj for djgpp.  i have gcc ver 2.8   .
it compiles and runs fine using Visual Studio.  but after i set up rsxntdj
as it told me to, i get error messages like syntax errors in the code.  i
can't even run the example program provided in the rsxntdj help file.  if i
try it, even a "hello world" prog, compiled using -Zwin32,  i get:

c:/djgpp/bin/ld.exe: cannot open -lc_app: No such file or directory
(ENOENT)

i followed everything to a tea.
maybe you can get the program running.  it shouldn't be hard.

there are only .cpp files and .h files (custom)
if you get it running and want to run a test program, just try a putSTR
command or the custom

DrawLine(x1,x2,y1,y2);  (exact punctuation)

thanks
