30 which defines iconv_t or declares iconv after this file, 2. when compiling
31 for LIBICONV_PLUG, we need the proper iconv_t type in order to produce
32 binary compatible code.
33 But gcc's #include_next is not portable. Thus, once libiconv's iconv.h
34 has been installed in /usr/local/include, there is no way any more to
35 include the original /usr/include/iconv.h. We simply have to get away

38 #include "iconv.h" or #include_next "iconv.h"
39 is small. They all do #include <iconv.h>.
40 Ad 2. The iconv_t type is a pointer type in all cases I have seen. (It
41 has to be a scalar type because (iconv_t)(-1) is a possible return value
