Subject: build: Activate warnings and LTO on *BSD.
X-Git-Tag: v0.7.3~30
X-Git-Url: http://git.tuebingen.mpg.de/versions/paraslash-0.3.2.tar.bz2.asc?a=commitdiff_plain;h=bbe5e72fc114e601fe2a6e6ec2b46b33c2def762;p=paraslash.git

build: Activate warnings and LTO on *BSD.

Newer versions of BSD ship compilers/packages which no longer
throw warnings, so activate the warnings on all platforms. Also LTO
(link-time optimization) seems to work on the test machines now,
so activate this as well.

Tested on FreeBSD-13.1 with clang-13.0.0 and on NetBSD-9.3 with
gcc-7.5.0.
