Hi,
I've noticed that the default color macros in pdcurses (BGR) are
not the same as the default in ncurses (RGB):
ncurses:
COLOR_BLACK = 0
COLOR_RED
COLOR_GREEN
COLOR_YELLOW
COLOR_BLUE
COLOR_MAGENTA
COLOR_CYAN
COLOR_WHITE = 7
pdcurses:
#define COLOR_BLACK 0
#ifdef PDC_RGB /* RGB */
# define COLOR_RED 1
# define COLOR_GREEN 2
# define COLOR_BLUE 4
#else /* BGR */
# define COLOR_BLUE 1
# define COLOR_GREEN 2
# define COLOR_RED 4
#endif
#define COLOR_CYAN (COLOR_BLUE | COLOR_GREEN)
#define COLOR_MAGENTA (COLOR_RED | COLOR_BLUE)
#define COLOR_YELLOW (COLOR_RED | COLOR_GREEN)
#define COLOR_WHITE 7
If no definition is made by the user the same program will look
different when including pdcurses' <xcurses.h> than when <ncurses.h>
is included.

Have you tested this? The values might be treated in different ways
internally. I assume you link with the library corresponding to the
included header.

Of course I tested it - I looked in the .h file only after I got
different colors in my game 
The libs were each linked with their own header. pdcurses linked with
ncurses' header results in no color support.

A-ha - I see now that I misunderstood the original post. Never mind.
Pardon my scepticism, I was just trying to prevent the spread of
potentially incorrect information.

It won't, if you consistently refer to colors by their symbolic names
(COLOR_BLACK, etc.), which is the recommended practice. If you want to
refer to colors by number, and have them look the same with ncurses and
PDCurses, then yes, you should probably define PDC_RGB when building both
the library and your app.

Yeah, I noticed that when I ported my games to Linux. Since it's not
possible to get the #define constants out of a dynamic library, it's
somewhat of an inconvenience. There are a lot of other inconsistencies
as well.

This is why these constants have names. Use the same name, and you get
the same color.
