 Thanks for the heads-up. What is the last command to fail when you run '= ;make V=3D1'?

Also, in src/Makefile, what are the values of PNG_CFLAGS, and of LIBIMAGE?<= br>
Also, what is the output of the following shell commands? (The session belo= w shows the output on Fedora 27.) Is the output correct for Arch Linux?
