otherwise it still using gcc 4.2. Is this normal?

IcedTea provides an additional step to the OpenJDK build process that allows
older JDKs to be used to build OpenJDK (the goal is to not require non-open
source/free tools to build OpenJDK).  It also provides replacement code for
the binary plugins that were initially release with the OpenJDK (I think
they have all been replaced in OpenJDK).

This additional step allows the use of Apple's JDK 5 to build OpenJDK 7
without requiring JDK 6 - which was not available when I started this
process.  This should work on PowerPC once Zero and Shark are integrated
into the BSD port thus bringing JDK 7 to PowerPC macs.
