Subject: Set CC to gcc by default.
X-Git-Tag: v0.1.1~5
X-Git-Url: http://git.tuebingen.mpg.de/?p=osl.git;a=commitdiff_plain;h=bc025530248c52e31a629b2a8943b2f68e919caa;hp=f55deeb0da0fe02cc3ff713e0a02057764b860a0

Set CC to gcc by default.

On systems where cc != gcc, compilation likely fails because we are
using quite some gccisms in osl. 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.
