[csw-maintainers] Problems with GCC Java compiler

[Dagobert Michelsen]

Hi folks,

I am again fiddling with gcc flavors and noticed a problem with gcj (not that it ever
worked on our release):

1. libiconv is needed, but no longer linked in

Although I didn't tinker with this the issue may be resolved easily.

2. Some obscure compilation error, I will take any advice here:
