Hi,

encouraged by the recent improvement in clang's C++ support, I tried 
building DragonFly's devd(8) with it but am getting:

clang -fno-color-diagnostics   -O -pipe  -I. 
-I/home/s/projects/dragonfly/src/sbin/devd  -g  -c devd.cc

/usr/include/wchar.h:78:1: error: declaration does not declare anything
typedef __wchar_t       wchar_t;
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

But what is the problem here?

Regards,
