utf8_decode() not declared

[janstary]

Compilation of ogginfo/codec_skeleton.c fails due to utf8_decode() not being declared.
Fixed in #33

This is present in 1.4.2 and the current git repo.

I also tried this and ran into the same problem:

make[1]: Entering directory '/depot/jjjj/vorbis-tools/ogginfo'
  CC       codec_skeleton.o

Could someone perhaps do a patch-release of vorbis-tools, or has it been abandoned already?
