| 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␊ |
