| 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().) */ |
