I found something interesting, on a debug compile. How is the file 
llib-lncurses used? Using the most recent roll-up patch 20030510, and 
comparing this file from one I did a debug build on a couple months ago, 
I see that the newest one has const on fmt, but the debug version does 
not (I am not currently linking against the debug version, but the rpm 
for the binary was created from it). That llib-lncurses file seems to be 
the key, as on the older one it has this:
#undef mvprintw
int     mvprintw(
                int     y,
                int     x,
                char    *fmt,
                ...)
                { return(*(int *)0); }

On this older one it removes the const version and puts non-const back 
in. I guess what I need is a new rpm based on all of the patches that 
have been out since 5.3, rather than one based on only part of the patches.
