Subject: Makefile.in: Avoid gcc warnings on non-linux systems.
X-Git-Tag: v0.3.0~59^2~1
X-Git-Url: http://git.tuebingen.mpg.de/?p=paraslash.git;a=commitdiff_plain;h=d2765e8ef91706453cdc6ed3fde89baf56ac718a;ds=sidebyside

Makefile.in: Avoid gcc warnings on non-linux systems.

-fdata-sections, -ffunction-sections, -Wl,--gc-sections, -Wstrict-prototypes
and -Wshadow produce quite a lot of warnings on at least NetBSD and MacOS. So
use these flags only on Linux.
