Can someone point me in the right direction? My package

isn't it on ARM? Then you should use explicit "signed char" as char
is unsigned by default on ARM (and other arches), see eg.

Thanks Dan, that got it, adding an explicit signed fixed the build.
you are welcome, there will be more packages suffering from the same
problem (I own at least one :-)), sometimes appending "-fsigned-char"
to CFLAGS will be easier.
Note that -fsigned-char changes the ABI, so it might have various
undesirable effects too.
Exactly. Because of this, I -fsigned-char should only be applied as a
last resort/work-around to mere program/application packages and not to
library packages, IMHO.
