------- Comment #3 from tprince at computer dot org 2008-05-11 17:26 ------- I see that the failing case is looking for a libiconv in the library to match the char ** prototype, and failing to find one, while the one in the actual library is set up for the const char ** version. The comment in codecvt_specializations.h indicates this should be taken care of by __iconv_adaptor, yet the link failure shows this is not working. I don't understand the usage well enough to know what to conclude, why some cases (do they also exercise __iconv_adaptor ?) work, while the unicode.cc cases fail to link at that point. This problem has been brought up by others in mail lists, but as far as I know no one wrote up a PR.
