Subject: build: Remove duplicate -Wno-unused-function.
X-Git-Tag: v0.5.4~46^2~20
X-Git-Url: http://git.tuebingen.mpg.de/?p=paraslash.git;a=commitdiff_plain;h=5e61409cae7999ec4372f7408ad2f7c078cd188d;hp=d67061d23fa2757b7d06328bfc9f4e5c3c733f40

build: Remove duplicate -Wno-unused-function.

We compile the .c files generated by gengetopt with this option to
silence a compiler warning. The option is first added to CPPFLAGS
and then specified again in the rule for the *.cmdline.o target. This
gets rid of the second instance.
