[rogueclone-devel] ncurses & control characters

[Michael L. <mle...@us...>]

I don't think anybody actually reads this mailing list but I will post my 
message anyway. Maybe it will be funny in a year or two.

I am trying to make rogue clone use curses again. The following program 
works just fine in Windows (win2k, djgpp, pdcurses). But in Linux 
(knoppix, gcc, ncurses) some of the characters are printed as control 
characters (like backspaces, not like ^D). If anybody can offer any 
insights, I'd appreciate it.

I have a feeling the mailing list may do something crazy to the single 
quotes in my code when it puts this message in the web archive. That would 
be the funny part, I guess.
