/* We would like to #include any system header file which could define | ||
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().) */ | ||
