+/* We would like to #include any system header file which could define
+ iconv_t, 1. in order to eliminate the risk that the user gets compilation
+ 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>.
+ Ad 2. The iconv_t type is a pointer type in all cases I have seen. (It
+ has to be a scalar type because (iconv_t)(-1) is a possible return value
+ from iconv_open().) */
