[cl-gd-devel] iconv and cl-gd

Dear cl-gd developers I know what iconv does quite well. I tried 'grep iconv ...' to figure out how it is used in cl-gd, and found nothing. Is link option -liconv really necessary? I built the cl-gd-glue shared library without the option and didn't have a problem so far(my client want to avoid GPL and LGPL softwares if it is possible) Thanks Jong-won Choi
