Agreed.  The HotSpot build is definitely quirky about allowing the
compiler to be overridden.  It actually seems to have gotten worse
in later releases (it includes a header file based on the compiler
name and it better be gcc).

Thanks for tracking this down!  I think the other jdk* ports also have
problems respecting $(CC) and $(CXX).  

I'll get this committed to jdk14.

It would be interesting to try the jdk15 port with gcc34 (or even the
gcc42 port rather than system compiler).  There will need to be some
more hackery to try that though I believe.
