Subject: Set CC to gcc by default.
X-Git-Tag: v0.1.0~4
X-Git-Url: http://git.tuebingen.mpg.de/versions/paraslash-0.3.1.tar.bz2.asc?a=commitdiff_plain;h=d2e63f5c74e8eaeef202d739637e9ae96264aa52;p=adu.git

Set CC to gcc by default.

On systems where cc != gcc, compilation likely fails because we are
using quite some gccisms in adu. So default to gcc but let the user
override the default by setting CC manually.

The straight-forward CC ?= gcc does not work with gnu make as make
assigns CC the default value "cc".

Thanks to Steffen Schmidt for pointing out this shortcoming.
