hi,
it seems the new wallet does not build with upnpc v 1.9 and after updating do v 2.0 neither.
i dont know what to do with these errors, maybe one of you knows

net.cpp: In function 'void ThreadMapPort()':
net.cpp:981:68: error: invalid conversion from 'int*' to 'unsigned char' [-fpermissive]
devlist = upnpDiscover(2000, multicastif, minissdpdpath, 0, 0, &error);
^~~~~~
net.cpp:981:74: error: too few arguments to function 'UPNPDev* upnpDiscover(int, const char*, const char*, int, int, unsigned char, int*)'
devlist = upnpDiscover(2000, multicastif, minissdpdpath, 0, 0, &error);
thanks!
