+   errors because some other system header file includes /usr/include/iconv.h
+   which defines iconv_t or declares iconv after this file, 2. when compiling
+   for LIBICONV_PLUG, we need the proper iconv_t type in order to produce
+   binary compatible code.
+   But gcc's #include_next is not portable. Thus, once libiconv's iconv.h
+   has been installed in /usr/local/include, there is no way any more to
+   include the original /usr/include/iconv.h. We simply have to get away
+   without it.
+   Ad 1. The risk that a system header file does
+   #include "iconv.h"  or  #include_next "iconv.h"
+   is small. They all do #include <iconv.h>.
