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