some entries in terminfo database want too many color pairs

[G. Branden Robinson]

Hi Thomas,

When building ncurses, I get this:

"terminfo.tmp", line 1232, col 36, terminal 'fbterm': limiting value of `pairs' 
from 0x10000 to 0x7fff
"terminfo.tmp", line 5363, col 36, terminal 'xterm+256color': limiting value of 
`pairs' from 0x10000 to 0x7fff
"terminfo.tmp", line 5395, col 36, terminal 'xterm+256setaf': limiting value of 
`pairs' from 0x10000 to 0x7fff
"terminfo.tmp", line 5442, col 25, terminal 'xterm+direct2': limiting value of 
`colors' from 0x1000000 to 0x7fff
"terminfo.tmp", line 5442, col 40, terminal 'xterm+direct2': limiting value of

"terminfo.tmp", line 5457, col 40, terminal 'xterm+direct': limiting value of 
`pairs' from 0x10000 to 0x7fff
"terminfo.tmp", line 5479, col 25, terminal 'xterm+indirect': limiting value of 
`colors' from 0x1000000 to 0x7fff
"terminfo.tmp", line 5479, col 40, terminal 'xterm+indirect': limiting value of 
`pairs' from 0x10000 to 0x7fff
"terminfo.tmp", line 8657, col 36, terminal 'dvtm-256color': limiting value of 
`pairs' from 0x10000 to 0x7fff

...and indeed it looks like the complaint is not spurious:

$ grep -B2 'pairs#0x10000' misc/terminfo.src
# dim, rendering those as green, cyan and gray respectively.

What should change?  The color/pair count limits or the terminfo
entries?  I perused curs_color.3x, thinking that perhaps since ncurses's
terminfo database is likely used by other curses implementations, that
the warnings might arise from ncurses using narrower data types for
color and pair counts than others, but that doesn't seem to be the case.

(Still, it's possible for a terminal to support more numerous colors
than _any_ library interface bothers to count, but that doesn't seem to
be the case here; the largest values above are 2^24, which fits in a
32-bit int.)

What am I missing?
