Ouch. The compiler doesn't grok its own include file.

I've seen error on another machine too. My fix was to set the CFLAGS so
that /usr/include would override /usr/include.dtk, but still allow
<iconv.h> to be found from my /opt/gnu:

  $ ./configure --prefix=/opt/gnu \
    CC="cc -O" CFLAGS="-I/opt/gnu/include -I/usr/include"

But maybe there is another solution? Does the compiler support a flag that
makes it grok the __VA_LIST__ in the first place?
