OpenJDK on Solaris Dev Express 1/2008?

[Kelly O'Hair]

I'm not sure what the state of the Makefiles are for building with gcc
on Solaris. It has been done in the past, from the artifacts I see in the
Makefiles, however, it won't 'just build', it will take some changes.

In general we focus on one compiler set per OS, the one that has
the most potential for performance and makes the most sense for that OS.
Takes a great deal of testing and performance tests to 'validate' that
even a particular release of a compiler isn't regressing us.

We will be going through that validation process as we change our
default JDK7 compilers to SS12 on Solaris, gcc4 on Linux, and
VS2008 on Windows.
