Thanks for your quick reply and efforts.
I have compiled it succesfully with gcc-2.95 on Atari FreeMiNT (using 
Aranym emulator on Linux Fedora)

Then I tried compiling img2png with gcc-4.1.2 on Fedora Core 7.
It still fails with these error messages:

gcc -I/usr/include -I/usr/include -O2 -Wall   -c -o img2png.o img2png.c

Maybe you can mail me your Suse-compiled img2png binary, to see if it runs 
correctly on my Fedora system also ?

I will cc this e-mail also to the freemint or aranym mailing lists. Maybe 
someone there can help to find a fix for this ? It's about a simple tool 
to convert Atari IMG images to PNG images. On my Aranym box I would like 
to have this tool available both on the Linux side and on the Atari 
(easymint) side. Forgive me if this i slightly off-topic.
