Thanks.  This is bad.  Is there no wchar.h on your system?  For
reference, which system is this?

The problem is that idn-int.h is installed into /usr/include/, so even
if I apply your fix to solve the problems inside libidn, there would
still be problem for all applications that include the libidn headers.

I'll bring up this on the gnulib list.
