Summary0005481: ISO C++ forbids forward references to 'enum' types
DescriptionThanks for fixing the previous build problem. However, a bad forward declaration in gnunet_hello_lib.h breaks my C++ application:

$ make install
Making install in src
make[1]: Verzeichnis „/home/stm/Entwicklung/dkgpg/src“ wird betreten
depbase=`echo dkg-gnunet-common.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\
clang++ -DHAVE_CONFIG_H -I. -I/home/stm/include -I/home/stm/include -g -O2 -Wall -MT dkg-gnunet-common.o -MD -MP -MF $depbase.Tpo -c -o dkg-gnunet-common.o &&\
mv -f $depbase.Tpo $depbase.Po

Do you have any idea how to solve this? Otherwise I suggest to move the declaration of enum GNUNET_ATS_Network_Type to some high-level header.
