And followup:

dcraw_emu/dcraw.c also accepts user_flip in degrees (e.g. 90, 270, or -90), to handle this too, add these lines before snippet in previous message:

if (flip > 89 || flip < -89)
{
flip = (flip + 720) % 360;
switch (flip)
{
case 90: return 6;
case 180: return 3;
case 270: return 8;
default: return 1;
}
}
