Comment 8 for bug 1806044

pcb-printf actually has quite a few tests. They're run using the glib testing framework though, not the run_tests.sh script. They're in pcb-printf.c at the end of the file: pcb_printf_test_printf().

I haven't looked at this much, but, I'm not sure that %mN is a valid format specifier. Perhaps it's new to pcb-rnd?

If the output is supposed to be dmil, I think the format specifier should be %mt.
