Thanks, this is helpful.

OK.  Same here.  I get a variety of different results with different
combinations of Cygwin version (1.5, 1.7), terminal type (DOS, xterm) and
with/without screen.  Without modification, the only combination that gives 256
colors for me is Cygwin 1.5, xterm, without screen.  All others give 8 colors,
and the colormap is garbled in the DOS terminals (big surprise).

However, in /usr/share/terminfo/s, there is a variety of screen* files,
including several named screen-256color*.  So it turns out that for me, running

TERM=screen-256color screen

gives 256 colors, at least in Cygwin 1.5.  Can you confirm this?

In Cygwin 1.7, I still only get 8 colors.  I'll report that separately as a bug.

Andrew.
