Subject: build: Add -Wunused-macros to CPPFLAGS on Linux.
X-Git-Tag: v0.5.5~32
X-Git-Url: http://git.tuebingen.mpg.de/?p=paraslash.git;a=commitdiff_plain;h=132ab22db97d57c688b2a4cda4a905aee17cf5b0;ds=sidebyside

build: Add -Wunused-macros to CPPFLAGS on Linux.

We already specify -Wunused which combines all -Wunused options but
does not activate the -Wunused-macros cpp warning.
