Tru64 Unix problem: --encondig=UTF-8

[Antonio Ake]

Hello,
I am working with 20010924 snapshot, I tried to compile a file and I had
this message error:
>>>gcc -02 -c spec/benchmarks/_201_compress/Main.java
spec/benchmarks/_201_compress/Main.java:0: unknown encoding: `ISO8859-1'
   This might mean that your locale's encoding is not supported
   by your system's iconv(3) implementation.  If you aren't trying
   to use a particular encoding for your input file, try the
   `--encoding=UTF-8' option.
My OS is Tru64 Unix v 5.0 Alpha
I already added the patches:
http://gcc.gnu.org/ml/java-patches/2001-q3/msg00466.html
and
