graphics/gdal 1.9.0 does not build on CURRENT

[Rainer Hurling]

Thanks for the update of graphics/gdal to version 1.9.0.

It builds fine on 9.0 (amd64), but fails on 10.0-CURRENT (amd64):

It seems there is a portability issue with ICONV_CPP_CONST like it is 
described in port/cpl_recode_iconv.cpp:l76ff ?

/* -------------------------------------------------------------------- */
/*      XXX: There is a portability issue: iconv() function could be    */
/*      declared differently on different platforms. The second         */
/*      argument could be declared as char** (as POSIX defines) or      */
/*      as a const char**. Handle it with the ICONV_CPP_CONST macro 
here.   */
/* -------------------------------------------------------------------- */

Please let me know, if you need more details.

Thanks again,
Rainer


P.S.: ports/166605 should be obsolete now?
