Bug#417568: art_misc.h doesn't mark some functions as 'extern "C"'

[Roderich Schupp]

Package: libart-2.0-dev
Version: 2.3.19-1

Hi,
while trying to rebuild kdelibs it failed beacuse it could not
find the functions art_alloc, art_free etc when linking
(though libart_lgpl.la was correctly specified for "libtool --link ...").
Turns out that these functions where taken as C++ functions
(i.e. with mangled names). art_misc.h is to blame -
functions were not marked as 'extern "C"', suggested patch below.

Cheers, Roderich
