Subject: build: make all char unsigned
X-Git-Tag: 1.0.17~14
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=0221be2f09c95280f98cf09474c03fc47a96bb1b;p=thirdparty%2Flldpd.git

build: make all char unsigned

This is something that may be used by the kernel later. char may be
signed or unsigned depending on the architecture, so catching that may
be difficult without this option.
