Subject:   My iconv (GLIBC 2.2) uses char** as the second
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/f1339c5685837ceff94d2aee40a0c2849fbe0ca0?ds=sidebyside

  My iconv (GLIBC 2.2) uses char** as the second
    parameter. altough it is the in-buffer for the
    character conversion. I added some very ugly
    conversion to strconv to make it compile. While
    being at it, I also reformated the whole file,
    it looks less like Assembler or Perl now.
