37 | /* We would like to #include any system header file which could define␊ |
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␊ |
