I see that a bit of code in 'tga.c' dealing with image orientation was
commented out because the compiler warned that it produced an invalid

Did you fix it with changeset 16721 [1]? I don't have time to compile
and check it ATM, but might package it tomorrow if it's a proper fix.
No it is not fixed yet. I fixed a different bug, which caused some sample
files to not be read at all.
While it would not surprise me all if there is an orientation bug in
GraphicsMagick, for the provided case, the image shown by ImageMagick
6.9.10-23 and GraphicsMagick is exactly the same.
The orientation which likely has issues is the exceedingly rare case
where the row pixels may need to be written in reverse.
Can this issue be reproduced independently?
