Who is selling GCJ commercial support ?

[P.O. Gaillard]

Hello,

I am currently evaluating GCJ as a development platform and would like to know 
who sells support for GCJ.

I would be very interested in feedback concerning :
  - Red Hat/Cygnus
  - Code Sourcery
  - Ada Core technology (do they have a partnership or support for GCJ since 
that already do Gnat and GCC ?)

  Thank you very much for your attention,

   P.O. Gaillard
