[fpc-pascal]text color problems under linux w/ocrt

In the process of porting an old DOS game to linux using fpc, I'm
having some trouble getting the textcolor(0)/textbackground(0) and
textcolor(8)/textbackground(0) color combinations to display properly
using ocrt and ncrt.  textcolor(0)/textbackground(0) displays as white
text on a black background (the same as
textcolor(7)/textbackground(0)), and textcolor(8)/textcolor(0)
displays as bright white text on a black background. (the same as

Interestingly enough, these combinations work as expected when using
the regular crt module.

I suspect this might be happenning because these color combinations
are being mapped to ncurses color pair 0 (with and without the bold
attribute), and in ncurses color pair 0 can't be modified via the
init_pair function.  Ncurses provides an additional function,
assume_default_colors, which can be used to modify color pair 0.
However, it seems that no wrapper for this function is provided in the
fpc ncurses package.  Is there a good reason for this?  Any
suggestions for a workaround to this problem?
