First, thanks for making the program available. I tried compiling it =
and running it against the attached cc1.ico file and got two SIGFPEs. I =
modified icod.c a bit (attached) and got through, but I am not sure that =
the generated xpm files are faithful to the original. Would you care to =
comment?
My platform is:
