[gclist] GCC 3.0 and GC?

[Daniel Wang]

New Languages and Language specific improvements: 
  The GNU Compiler for the Java(TM) language (GCJ) is now integrated and
  supported, ...  and the Boehm conservative garbage collector.

Other significant improvements: Garbage collection used internally by the
   compiler for most memory allocation instead of obstacks.

So does this mean GCC is now using the Bohem conservative collector? Or is
gcc using a different GC internally. I'm generally, curious as to why the
GCC developers decided to take the plunge and adopt GC.
