| 38 | + iconv_t, 1. in order to eliminate the risk that the user gets compilation |
| 39 | + errors because some other system header file includes /usr/include/iconv.h |
| 40 | + which defines iconv_t or declares iconv after this file, 2. when compiling |
| 41 | + for LIBICONV_PLUG, we need the proper iconv_t type in order to produce |
| 42 | + binary compatible code. |
| 43 | + But gcc's #include_next is not portable. Thus, once libiconv's iconv.h |
| 44 | + has been installed in /usr/local/include, there is no way any more to |
| 45 | + include the original /usr/include/iconv.h. We simply have to get away |
| 46 | + without it. |
| 47 | + Ad 1. The risk that a system header file does |
| 48 | + #include "iconv.h" or #include_next "iconv.h" |
| 49 | + is small. They all do #include <iconv.h>. |
| 50 | + Ad 2. The iconv_t type is a pointer type in all cases I have seen. (It |
| 51 | + has to be a scalar type because (iconv_t)(-1) is a possible return value |
